I have a keyboard in my room back home, but it isn't really the same. Playing bits of white plastic aren't the same pounding on dead elephant tusks. (I say that as a joke, but my old piano was so old, it might have actually had proper ivory in it!)
I think the overplaying was caused by her winning this 'Upcoming new artist' poll run every year by the BBC. There was all this expectation put upon her shoulders, so when Chasing Pavements came out, it was just played to death. US didn't really hear of her 'til the SNL episode where Sarah Palin guest starred: massive ratings launched her into the relative mainstream over there.
