They really should have done some research on the music IMO. Yeah, the music doesn't break the game, but think about it (not everyne mutes it), you hear the music 90% of the time when in-game. It'd be nice if they actually did a poll or research or EVEN put out top genres that fit the scene.
It still irks me they have no Metal station, yet it appears a lot of the pedestrians seem to wear death metal-like band t-shirts. As I sit here listening to Napalm Death, I feel like there would be so much more of a feel if they put in Bay Area thrash metal. I don't know a single person who listens to the garbage on Channel X radio. Hell even the Classic Rock Station is caca..only a few good songs..and out of all the Queen's big hit songs you put on Radio Gaga? That song is butt cheeks.
Example : Overkill (one of the first thrash metal bands from Cali)
I'd love to drive down Vinewood mowing people down to Overkill - A Time to Kill
