I wish they'd integrate the soundtracks from all the other versions of GTA into the game. I loved the classical station in GTA III, the 80's music in Vice City, the country station in San Andreas, and the jazz station in GTA IV.
Yes, I want Eminence Front and Running Down A Dream back from San An.
I would like Radar Love, seeing as they said it would be in it before it was released. Born to be Wild would be cool. Any Pink Floyd (never going to happen), Foo Fighters, Tom Petty, Iron Maiden, Santana. I was dissapointed by the Country selection, On the Road Again and Take Me Home, Country Road would have been great additions.
