Grand Theft Auto V makes it's debut on September 17th, but an accidental leak caused the soundtrack information to be released early. Users in Europe who pre-ordered the game were able to gain access to parts of the full game. Sony apologized for the leak, but their problem is our gain, as both Odd Future's Tyler, the Creator and A$AP Mob's A$AP Rocky have tracks on the upcoming video game. 

Here's "Untitled" (It isn't clear if that is the name of the track or if it is unknown at this time) by A$AP Rocky, with Tyler's "Garbage" below.
