The legendary guitarist Carlos Santana teamed up with Nas and hit us with a cover of the 1981 AC/DC classic "Back In Black." A Ne-Yo demo for a young pop singer-songwriter surfaces. A snippet of a T-Pain and Busta Rhymes song released many moons ago hit the net in its entirety. John Legend and The Roots hook up with Pete Rock and CL Smooth.
