For starters, infamous singer, songwriter, guitarist John Mayer has a song entitled, "Who Says" (2009). Singer, songwriter Selena Gomez ALSO has a song with this same title (2011). 

Every time I see the title in John Mayer's discography, I instantly think of Selena Gomez's work instead of his own. In fact, I can't even hardly remember how John Mayer's tune goes; it's only Selena Gomez up in this head. 

SO... I propose that John Mayer should take this opportunity to either cover Selena Gomez's song in good nature, or to prank his audience as if he were about to sing his "Who Says", when really he starts singing Selena Gomez's "Who Says".

I believe this is what we need in the music industry right now; some lighthearted fun to comment on the natures within the community, such as similar song titles. 

After all, who says we're not perfect?
