I think this is something anyone who has played any Grand Theft Auto game can relate to: driving around, just for the hell of it, flicking through radio stations, laughing at Lazlow's shenanigans, listening to the well chosen songs from the game's soundtrack. This new Android thingy, allows you to do this in real life by cramming all the soundtracks from all the games into one app.
This is genius and I can't understand why it hasn't been done up until this point (probably licensing)! The app contains almost every radio station from GTA III, GTA Vice City, GTA Liberty City Stories, GTA Vice City Stories, GTA San Andreas and GTA IV. A few radio stations are missing, but apparently the team behind the app is working on that for future updates.
