When Taylor Swift puts out a song, everyone has an opinion: The music critic, the die-hard fan, the hater (who's gonna hate, hate hate) -- and yes, the person who inspired the track.
Ed Sheeran and John Mayer performed 'Thinking Out Loud' at the 2015 Grammys and the PopCrush editors were literally weeping from the beauty of it all.
John Mayer surprised audiences on his Australian tour by performing an unexpected cover of Beyonce’s love song ‘XO.’ The singer and his fans enjoyed the performance so much that he just released a studio recording on iTunes.
