Chamillionaire Badazz Slow-Mixes (Self-released, 2011)

Chamillionaire, everyone's favorite globetrotting recluse, held a contest on his Web site back in May. The rules were plain enough: Create a 12-song mixtape that incorporates his "This Is My World," "Slow City Don" and "Chandelier Ceiling" into the fray, turn it in, then wait. The prize was, basically, an official co-sign from Chamillionaire,, who promised to send it to all of the blogs and not erase the winner's name. This tape came away the winner.

Yallmustaforgotability: 98 percent

The novelty of the tape will be remembered, but ultimately, when people talk about it, they'll say things like, "Remember that Badazz Slow-Mixes tape, the one where Cham went in on that Miguel song."

Why This Tape Works: Chamillionaire helped build his empire by thieving beats from folks. And his bumblebee drone has always been a weapon he's wielded with precision, especially when he was pulling the innards out of an R&B song. And that's pretty much what he does for the entirety of this tape.

The Artist That, After Listening To This Tape, Makes You Say, "You know, Chamillionaire should really do a song with that guy": Surprisingly, it's Frank Ocean, this year's most interesting insta-superstar. He manages to outdo J. Cole, Z-Ro, Big K.R.I.T. (just barely), Drake and more. That guy's probably not going anywhere soon.

Song That Makes You Realize Z-Ro Could've Really Been A Giant Had He Had More Opportunities To Work With Outside-Houston Production: The eighth song on the track is the best "I Hate You" redo, that one where his vocals are laid out over Usher's idyllic "There Goes My Baby" beat.
