Flashback, makes me fell like I'm Tony Montana cruising around Miami. At least 3 of those songs on Flashback are on the soundtrack to scarface. Flashback gets real old too fast so Jah is the other station I like. All of the radio stuff is pretty good though.
The voice talent is also very good in this game, they got actual actors. I thought the voices of guys like Luigi and Ray the crooked cop sounded familiar. Can't remember their real life names tho, it's in the credits in the game manual tho.
