SURF finally came and it is going to be the soundtrack of everyone’s summer. The super-chill collaborative effort by Donnie Trumpet and the Social Experiment not only makes a serious case for 2015’s most valuable hip-hop album to date thus far, thanks to Chance the Rapper and the rest of DT & TSE, but it has some serious cameos that add to the fun.

Now that we've had time to digest every single uncredited feature (and credit the tracks appropriately), we decided to pick and choose some of the best guest appearances. What's your favorite feature? If you missed the free album, you can grab it below, then head on to read through for the top 7 features on SURF.
