Adore You being best... ehh.. SMS being worst
I guess I can understand why, but I definitely don't agree.
As for BJ - what kind of 100% accurate tea!?!?! Til It's Gone is the best and CWY is easily the worst, and the only Britney song I've ever hated and had to delete, too. Just a disaster.
Successes are all nice, though I don't agree with Xtina being there... or at least not in the top 5. Flops are obvious. Nelly was 2012 but oh well.
Her flop was so catastrophic that it went into the next year.
