The end credits of the game list Mark Mothersbaugh and Josh Mancell for music and Larry Hopkins for additional music.

The game's wiki states that Mothersbaugh was only involved in music production with Mancell (primarily) and Hopkins handling composition. As far as I can tell, this is uncited and has lead to a whole host of websites regurgitating the same information - leading to the crediting we currently have on this page.
Does anybody have a solid source about how the music was handled? Otherwise, I'm thinking the staff roll is the best information source we have and that should be reflected.
