Good news for fans of Grand Theft Auto's musical stylings, as Rockstar has announced the radio stations from many of the GTA games are now on Spotify and iTunes. Grand Theft Auto III, Vice City, San Andreas, Liberty City Stories, Vice City Stories, Chinatown Wars, GTA IV, and Episodes from Liberty City are all accounted for on both platforms, so no matter which GTA game you've played, you'll hear something familiar. One minor issue is some songs may be missing due to not being available on Spotify and/or iTunes just yet, but Rockstar hopes to change that if possible. Commercials featured on the radio stations can be checked out at The Advertising Council repository, although ones from GTA IV are still on the way.
Be sure to head on over to the source to check out all the stations and how to access them on Spotify and iTunes.
