We can hate him all we want for how he conducts himself in his personal life, but when it comes to music, John Mayer can’t be messed with. This guy can write a tune and sing it like the best them. His new tune ‘Half Of My Heart”, the third single off his current Battle Studies album, debuts it’s video today on People.com and the song is being released to radio as well. The song is catchy and cool, it’s got that John Mayer edge to it and his voice sounds amazing. Through his lyrics, you can see that John is still trying to figure it all out. It features Taylor Swift, which I cannot understand for the life of me why, but thankfully, she’s not in the video. She sings for a few seconds and is so not needed. The video features Mayer at his best, singer and songwriter eating up the camera.
