John Mayer's new album Battle Studies is sure to be something of classic stature; he's an awesome musician and an artist that clearly lives and breathes his craft. Taylor Swift brings her sweet voice to this newest cut from the album, entitled Half of My Heart. I like this song because it's so open, he really knows how to articulate a man's sentiments. Battle Studies - November 17th, review coming soon...
