If you want to recreate the hijinks of Grand Theft Auto 5 in the real world streets of Los Angeles... don't. You'll hurt someone and get arrested. But, here's a safer alternative: you can have the game's soundtrack playing in your car.
The three album soundtrack is now available on iTunes. Each album can be purchased individually for $9.99, or as a full compilation for $24.99. The first volume focuses on "Original Music," featuring original music from various artists made specifically for GTA. The second volume focuses on the original score--a first for the franchise. Finally, the third volume focuses on the in-game radio, featuring "snippets" from every station in the game. Unfortunately for fans, the 19 track selection is far from comprehensive.
