Actually VC's the only one I didn't like, GTA3's soundtrack shits on it easily, for me.
1. San Andreas (Radio Los Santos, Playback FM, SF-UR, User track... all of them except for K-DST, K-Rose and Radio X.)
2. Vice City Stories (All of them were good except for V-Rock. My favorite is definitely Fresh 105 FM.)
3. GTA III (All the stations were cool except for Double Cleff. My fav: MSX and Flashback)
4. Liberty City Stories (Not so good as III, but I only disliked Double Cleff here and my favorites are the same as III.)
5. Vice City (Only Wildstyle, the rest were weak IMO.)
