ROAR!

WCS had huge impact. Nobody will remember Roar in a decade, there's nothing about it that differentiates it from yet another Katy single.

Roar.

The Whip My Hair rip-off isn't remembered.

Roar TBH

So tired of these charts now days....like We can't stop was a hit in Colombia...and don't look for its peaks because it was probably....#120. whatever but EVERY party I go to they put WCS even to this day...Roar is nowhere to be found.

.

I think WCS because it will be the big breakout for Miley.

Roar is just another Katy song.

Roar. Should've been Wrecking Ball instead.

Roar doesn't have anything to differentiate itself from any other pop single out there - no remembered performances, videos, etc. We Can't Stop was the party anthem of the summer with a controversial video and performance that were both talked about for months. My vote goes to WCS.
