T-Pain teased his long-lost collaborative project with Lil Wayne yesterday when he shared the cover art alongside a caption that read, "Do it?"

A couple hours later, he elaborated, "This ain't for y'all new niggas. These the lost files from '09 and I'm tired of em just sittin on my hard drive. #FreeC5."

For anyone calling his bluff, Pain just dropped it on SoundCloud and YouTube. And, whether "lost files from '09" or not, this one's worth diving into if you're a fan of either of these guys. The project has been teased since Lil Wayne first mentioned it to an MTV reporter way back in 2008 and it's finally here. Listen below.
