This is a track from American Heavy Metal band Mastodon's fifth studio album, The Hunter. The song is about a video game that mixes asteroids with hemorrhoids. Drummer/vocalist Brann Dailor told Kerrang!: "The lyrics to this are really aggressive but pretty childish. They go, 'I want to drink some f---ing blood/ I want to break some f---ing glass. I want to turn you inside out, I want it all.' We named it after this video game at the studio because it sounded silly."
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
