The following article contains an answer for the question: What song has mid-tempo riffing, followed by a bass solo at half-tempo? , can you please find it?   "The Thing That Should Not Be" was inspired by the Cthulhu Mythos created by famed horror writer H.P. Lovecraft, with notable direct references to The Shadow Over Innsmouth and to Cthulhu himself, who is the subject matter of the song's chorus.  It is considered the heaviest track on the album, with the main riff emulating a beast dragging itself into the sea. The Black Sabbath-influenced guitars are downtuned, creating slow and moody ambiance.

The guitar passage at the end of each verse was Hammett's imitation of the sort of music he found in war films. The syncopated riffing of "Leper Messiah" challenges the hypocrisy of the televangelism that emerged in the 1980s. The song describes how people are willingly turned into blind religious followers who mindlessly do whatever they are told. The 136 beats per minute mid-tempo riffing of the verses culminates in a descending chromatic riff in the chorus; it increases to a galloping 184 beats per minute for the middle section that climaxes in a distorted scream of "Lie!". The title derives from the lyrics to the David Bowie song "Ziggy Stardust". "Orion" is a multipart instrumental highlighting Burton's bass playing. It opens with...
