T-Pain is about to release Revolver, but in true T-Pain fashion, he has a free mixtape for us. Prevolver is a 30 track mixtape featuring Lil Wayne, Birdman, Field Mob and more. The best part is that it's free and you can get it below. You can also grab the Pree Ringz mixtape below.

T-Pain is one of the more creative artists when it comes to his marketing.  In addition to giving his fans the Prevolver mixtape for free, he also someone a chance to guest star it.   While you're getting all this free music, you should probably check out the T-mixes as well.
