Adele is the consummate live performer, but when she sang All I Ask at the Grammys Monday night, she sounded a bit off.

Was Adele, the most gifted songstress of our era actually...flat? No, it can't be. It must be sound issues. The mic was actually placed on the piano strings! Her guitarist was trying to sabotage her! Whatever the case, Grammys sound issues or Adele actually faltering a bit, Twitter was not happy. Because when Justin Bieber sounds better than you, something's not right.
