I've played 3, Vice City, Vice City Stories and San Andreas, and I think my favourite 2 stations are Emotion 98.3 and Wave, 103 but I like Flash FM a lot too. In San Andreas, I like about half the songs on both Radio: X and K-DST so I divide my time between those. V-Rock seems pretty good from what I've heard of it but I'm usually able to find something I like more on the other 3 channels which I usually listen to.
