Remember Jay Sean’s mixtape The Mistress? Oh come on, it was really good. It came out last year? Well, I guess Jay Sean is going to have to take you back to school as he returns with his mixtape cut, “Sex 101″ featuring his YMCMB brethren Tyga. The track is actually pretty good, nice melody, dope verse by Tyga. His album Worth It All is coming…eventually?
