Black Hole Giga Drill is a movement of the song Bōsōzoku Symphonic; the eleventh song on the album 'All The Lights In The Sky'. An extended version of BHGD was released on All the Lights in the Sky 「COMPLETE」. There is barely any difference, lyrically, between the two, except for the fact that "All the lights in the sky!" is repeated four times in the extended version, not two.
