Which GTA has the best tracklist?

[Maka]

This is really hard. Nearly every GTA I've played has had at least one great tracklist.
For GTA III, it was Rise FM's progressive trance channel.
For Vice City, it had various awesome radiostations, be it disco, electro/hiphop or rock music.
San Andreas had Radio X's rockstation, SF-UR's classic house music station, and not to forget the great Radio LS.
Gta IV would be one of the rock stations, the Hiphop station (forgot its name), and of course Electrochoc.
