Tu Hi Mera by Mithoon. I don't think I have heard anything quite as soulful since Delhi 6. This guy, Mithoon, has a way of touching a chord with his listeners. Of stirring their souls. The music, the words, and the vocals are loaded with emotion and are beautifully touching. You have absolutely got to hear this one.
On a slightly different note, if you haven't yet checked out Ranaji from Gulaal, it's not to be missed either. One of the more amusing pieces of music in recent times. Adorably endearing.
