As much as I love AC, I think I have to go with TGIFY too. AC has superior vocals IMO, but there is something that just "clicks" with TGIFY. I know
the consensus among many is that this song didn't deserve a #1, and though it may not be her most memorable hit as the years pass, I give TGIFY the edge
for it's beautiful melody and for the awesome, awesome production by JJ and TL which I feel make it a standout track.
