John Mayer collaborated with Katy Perry for his sixth studio album "Paradise Valley". His album sales are quite disappointing in U.k but if he releases "Who You Love", it will help them a lot..He has already released it in U.S.A..It's not something special but it's not bad though..Give it a try..

 

I don't know why, but I cannot stand John Mayer.. I really just want him to leave the scene and go away
