Cream's Sunshine of your Love came out in 1967, not 1968 as the game states.
This game incorrectly labels the band Dead Kennedys (original artist of Holiday in Cambodia) as The Dead Kennedys.
While The Sex Pistols' "Anarchy in the UK" came out in 1977, the "2007" label is correct. The original master track could not be located, so the band re-recorded the song for the game.
When one plays "Monsters" by Matchbook Romance in quickplay, during the final verse, the singer is not moving his mouth, but lyrics from Matchbook Romance's lead singer are heard. This is only evident in quickplay because in any other modes it is playable in (e.g. co-op career), the singer is not on stage.
In at least the Wii version, sometimes when Slash is playing, it is evident that his hands are not holding the neck of his guitar.
