I think it's pretty cool. For some reason, I wasn't WOW'd by it like I thought I would be, but that's probably because we had so many parts of the song before the FULL song came out, so I already knew exactly what it was going to sound like.

I think, if she does this for Days, I'm not going to listen to more than one of the previews because it really ruined the effect of finally getting the full song for me.
On the other hand, I do think it's basically like a new version of Will that drags on and on and is more suited for GUILTY than (miss)understood.
