TheSingingMixer: #JohnMayer’s #HalfOfMyHeart is a testament to how impossible it is to be #halfinlove! @Mattnification crafted a beautifully delicate, yet moving 3 #guitar #cover & was kind enough to let me #collab on #lead! It’s a lovely song, so if you want to #takethelead & #joinmycollab, by all means, do! #tsm
