I don't even like Gaga THAT much anymore but I'm not that against her to say she didn't change the whole pop scene when she came out. She definitely had some impact
I will never see Gaga's impact in music, like where is that impact that y'all talking about when she always serves the same generic EDM mess. The little impact that she had was, maybe, in fashion.
Gaga isn't revolutionary dance-pop/electropop was already on the way [back in the case of dance-pop] in by the time she debuted.
Nobody said "revolutionary" the OP is asking if she had any impact on music at all. but it's kinda nice that that's the word that comes to your mind when you enter a Gaga thread
