Rockstar's "Grand Theft Auto V" is a predictably enormous hit, and it comes loaded with a big soundtrack. As previously reported, the game features 17 radio stations curated by the likes of Flying Lotus, Wavves, Twin Shadow, and others.

Now, the music has been released digitally via iTunes. There are three volumes. First, a collection of original music with contributions from Flying Lotus, Tyler, the Creator, Wavves, Twin Shadow, Neon Indian, HEALTH, OFF!, A$AP Rocky, Yeasayer, and more. The second volume contains the original score, which was created by a collaboration between Tangerine Dream, the Alchemist, Oh No, and video game composer Woody Jackson. DJ Shadow took the score's stems and mixed them into an album. The third volume features selections from across the 17 radio stations, including tracks by Flying Lotus, Jai Paul, Bob Seger, Toro Y Moi, and more.

The volumes can be purchased individually or as a bundle-- find tracklists and previews here.
