Alright yeah, finally got my hands on GH3 and I beat it yesterday. Yeah, those WERE the album artists. But I can tell you with absolute certainty that on GH2, one of two scenarios is undoubtedly true:
Either those were not the album artists, or they did some SHITTY live recordings, 'cause GODDAMN that entire game, none of the songs sounded right.
But yeah, sound quality, music, etc. on number 3 was fucking fantastic. Loved the game, especially the end battle and credits sequence. Fucking epic.
NOTE: I don't care who you are or how many savage death metal mutilation bands you listen to, if you do not like "Devil Went Down To Georgia" you deserve to be shot. 'Nuff said.
