ARR didn't look comfortable on stage singing (not too surprising since he usually sings with his keyboard and is more of a studio singer than a live performance singer). He was singing off tune (baisura), esp "Tere Bina". I don't fault him for that entirely, since the the sound system had problems (the mike volumes were very low) and certain tracks were almost inaudable. What happened to the nine song medley? LOTR music? Pray For Me Brother? He only sang two songs (Khalbali and Tere Bina).
BTW, I'm very happy he won the best music award, but he should have won the best BGM award too.
