Given the question: Information:  - Virgin Records is a major record label first founded by English entrepreneur Richard Branson, Simon Draper, Nik Powell and musician Tom Newman in 1972. The company grew to be a worldwide phenomenon over time with the success of its platinum performers such as Janet Jackson, Roy Orbison, Devo, Genesis, Keith Richards, the Human League, Culture Club, Simple Minds, Lenny Kravitz, dc Talk, the Smashing Pumpkins, Mike Oldfield, Spice Girls and more on their list of artists. It was later sold to Thorn EMI in 1992.  - Michael Gordon "Mike" Oldfield (born 15 May 1953) is an English musician and composer. His work blends progressive rock with world, folk, classical, electronic, ambient, and new-age music. His biggest commercial success is the 1973 album "Tubular Bells"which launched Virgin Records and became a hit in America after its opening was used as the theme for the film "The Exorcist". He also recorded the 1983 hit single "Moonlight Shadow" and a rendition of the Christmas piece "In Dulci Jubilo".  - Universal Music Group, Inc. (also known as Universal Music Group Recordings, Inc. and abbreviated as UMG) is an American-French global music corporation that is a subsidiary of the Paris-based French media conglomerate Vivendi. UMG's global corporate headquarters are in Santa Monica, California.  - Musica universalis (literally universal music), also called Music of the spheres or Harmony of the Spheres, is an ancient philosophical concept that regards proportions in the movements of celestial bodiesthe Sun, Moon, and planetsas a form of "musica" (the Medieval Latin term for music). This "music" is not usually thought to be literally audible, but a harmonic, mathematical or religious concept. The idea continued to appeal to thinkers about music until the end of the Renaissance, influencing scholars of many kinds, including humanists. Further scientific exploration has determined specific proportions in some orbital motion, described as orbital resonance.  - The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.<ref name="doi10.1146/annurev-astro-081913-040012"></ref> It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System. About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.  - A record label or record company is a brand or trademark associated with the marketing of music recordings and music videos. Often, a record label is also a publishing company that manages such brands and trademarks, coordinates the production, manufacture, distribution, marketing, promotion, and enforcement of copyright for sound recordings and music videos; conducts talent scouting and development of new artists ("artists and repertoire" or "A&R"); and maintains contracts with recording artists and their managers. The term "record label" derives from the circular label in the center of a vinyl record which prominently displays the manufacturer's name, along with other information.  - A planet is an astronomical body orbiting a star or stellar remnant that The term "planet" is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such.  - Island Records is a Jamaican-English record label that operates as a division of the Universal Music Group (UMG). It was founded by Chris Blackwell, Graeme Goodall and Leslie Kong in Jamaica in 1959. Blackwell sold the label to PolyGram in 1989. Both Island and another label recently acquired byPolyGram, A&M Records, were both at the time the largest independent record labels in history, with Island in particular having exerted a major influence on the progressive UK music scene in the early 1970s.   - Progressive rock (shortened as "prog"; sometimes "art rock", "classical rock" or "symphonic rock") is a broad subgenre of rock music that developed in the United Kingdom and United States throughout the mid to late 1960s. Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing.  - In celestial mechanics, an orbital resonance occurs when two orbiting bodies exert a regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of two small integers. The physics principle behind orbital resonance is similar in concept to pushing a child on a swing, where the orbit and the swing both have a natural frequency, and the other body doing the "pushing" will act in periodic repetition to have a cumulative effect on the motion. Orbital resonances greatly enhance the mutual gravitational influence of the bodies, i.e., their ability to alter or constrain each other's orbits. In most cases, this results in an "unstable" interaction, in which the bodies exchange momentum and shift orbits until the resonance no longer exists. Under some circumstances, a resonant system can be stable and self-correcting, so that the bodies remain in resonance. Examples are the 1:2:4 resonance of Jupiter's moons Ganymede, Europa and Io, and the 2:3 resonance between Pluto and Neptune. Unstable resonances with Saturn's inner moons give rise to gaps in the rings of Saturn. The special case of 1:1 resonance (between bodies with similar orbital radii) causes large Solar System bodies to eject most other bodies sharing their orbits; this is part of the much more extensive process of clearing the neighbourhood, an effect that is used in the current definition of a planet.  - EMI (officially EMI Group Limited, originally an initialism for Electric and Musical Industries and often known as EMI Records and EMI Music) was a British multinational conglomerate founded in March 1931 and was based in London. At the time of its break-up in 2012, it was the fourth-largest business group and family of record labels in the recording industry and was one of the big four record companies (now the big three). Its EMI Records Ltd. group of record labels included EMI Records, Parlophone, Virgin Records and Capitol Records. EMI also had a major publishing arm, EMI Music Publishingalso based in London with offices globally.  - Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."  - Music of the Spheres is an album by English musician Mike Oldfield , released in the United Kingdom on 17 March 2008 . The album , Oldfield 's second album with Mercury Records and his first classical work , is based on the concept of a celestial Musica universalis . The album features New Zealand soprano Hayley Westenra ( on `` On My Heart '' ) and Chinese pianist Lang Lang on six tracks . Music of the Spheres was nominated for a Classical Brit Award in 2009 .  - Tubular Bells is the first album by English musician Mike Oldfield, recorded when he was 19 and released in 1973 when he was 20.  - The term harmonic in its strictest sense describes any member of the harmonic series. The term is employed in various disciplines, including music and acoustics, electronic power transmission, radio technology, etc. It is typically applied to repeating signals, such as sinusoidal waves. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called 1st harmonic, the following harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz.  - Mercury Records is an American-based record label owned by Universal Music Group. In the United States, it operates through Island Records; in the UK, it is distributed by Virgin EMI Records.  - "Moonlight Shadow" is a song written and performed by English multi-instrumentalist Mike Oldfield, released as a single in May 1983 by Virgin Records, and included in the album "Crises" of the same year. The vocals were performed by Scottish vocalist Maggie Reilly, who had been collaborating with Mike Oldfield since 1980. It is Oldfield's most successful single, reaching number one on a number of charts around Europe.    What entity does 'music of the spheres ' has the relation 'genre' with?
