Shake it off. Tbh, we were all thinking she would flop. Or at least perform significantly less well. Not to say that it's a risky song in general, but for Taylor it seemed like it was.
Idk why we thought she would flop, considering RED singles were already very pop
Shake It Off, everyone thought she would flop cause she left country and went to full pop. But if a different artist made the song then neither would be risky.
