New Music 101: John Mayer and Katy Perry ‘Who You Love’

The real life couple of John Mayer and Katy Perry are now a duet couple as well. John and  Katy have just released a sure-to-be hit single called 'Who You Love.'

John Mayer boasts 22 hit songs and 7 grammys in his career thus far. Strangely enough he has yet to hit #1. Perhaps this will be the magic potion that changes that?

Not to be outdone, Katy Perry has charted 15 hit songs and hit #1 seven times. She's also lent her voice to 3 'Smurfs' movies and has graced 11 different television shows, mostly as herself.

Enjoy 'Who You Love' by John Mayer and Katy Perry.
