No, just no. DH would've been #1 with or without Grammy performance. The perfomance of last night was really bad, overproduced, Katy sang really bad, so, the Grammy was not a factor to Katy's lead.
And I can't with some of you dragging Lorde sales when she got a song with 9 weeks in the #1, even Katy never made that.
EDIT: umich, stop! Really! You're becoming the most annoying and hypocrital Katy stan. Saying you don't care about Grammy when you put "11x grammy nominee" under your nickname. Obvoiusly you are preseed because Katy doesn't have any grammy and you will deal. Stay mad, hater.
