Given the question: Given the below context:  Kill 'Em All features intricate riffing reminiscent of the NWOBHM bands played at high velocity. The album is considered crucial in the thrash metal genesis because it introduced fast percussion, low-register chords, and shredding leads to the genre. Hammett played some pentatonic patterns in addition to his breakneck solos. Ulrich adopted a double time snare pattern that would become a mainstay on Metallica's subsequent albums. Hetfield's vocals evolved from the melodic wail on No Life 'til Leather to a rough-edged bark, and the entire band played faster and more accurately on Kill 'Em All. Music writer Joel McIver said Burton's and Hetfield's performances were nearly virtuosic, because of the smooth-sounding bass of the former and the precise picking skills of the latter. According to journalist Chuck Eddy, the juvenile lyrical approach to topics such as warfare, violence and life on the road gives the album a "naive charm". The musical approach on Kill 'Em All was in contrast to the glam metal bands who dominated the charts in the early 1980s. Because of its rebellious nature and Metallica's street appearance, it appealed to fans who were not into the mainstream of hard rock. "Phantom Lord" is a lyrical nod to devilry. The song begins with synthesized bass drone and contains a middle section with clean, arpeggiated guitar chords. Written by Mustaine, its central riff is in NWOBHM fashion. "No Remorse" is a mid-tempo song which suddenly accelerates its tempo in the fifth minute. The song is about not feeling any remorse or sense of repentance during battle. "Seek & Destroy" was inspired by Diamond Head's "Dead Reckoning" and is the first song Metallica recorded during the Kill 'Em All sessions. Hetfield wrote the main riff in his truck outside a Los Angeles sticker factory where he was working. Because of its simple, one-line chorus, the song became a permanent setlist fixture and a crowd singalong. "Metal Militia", one of the fastest songs on the album, is about heavy metal's way of life and nonconformity....  Guess a valid title for it!
The answer is:
Kill 'Em All
