A bit overrated but definitely not forgettable, esp as it (and the video) is already appearing on all sorts of important best-of lists.
I think a sign of its power isn't how many popstars started copying it...it's the opposite: despite its huge success, it hasn't had any imitators (other than Judas
, but she doesn't count) b/c it's so outside the box for a big popstar and it's pure Gaga. It has her fingerprints all over it. Truly an example of a song only she would do.
