T-Pain and Lil Wayne's musical relationship has given us some of the most memorable song's of this generation, and today Pain has liberated an unreleased collaboration between the two titled "Let Me Through." The duo, who also affectionately call themselves "T-Wayne" trade bars on the sparse beat which gives T-Pain room to show off his exceptional lyrical skills. Lil Wayne's verse is a show stealer however, as he continues his streak of dope verses this year as he stands proudly as "Cash Money's mascot." Stream the song below and buy T-Pain's new compilation album Happy Hour: The Greatest Hits on iTunes here.
