unless you mean just musically, she definitely has. the clothing, videos, image, performance, she pushes the boundaries and whether you think the way she does that is good or not you cant deny she does. but if you do just mean musically then fair enough its down to opinion. but no pop singer has made the kind of instant impact that she has done in a long time, fact
i know, but what im saying is its ignorant to say you dont like it because "all pop musicians are talentless people."
