It's just missing...something. It doesn't have the same "oomph" that the album version has, which is a shame, because it's probably the only song on that whole album that I actually like.
I like it. The middle eight was kind of weak and I found myself missing the auto-tuned part, but other than those I liked it a lot. Then again, I just love this song to death and it's really hard for fun. to do anything to make me dislike this one.
