I fully admit that I am somewhat out of the loop.

I've heard plenty of everyone she has gone after on Twitter. But I am unclear as to if I'm familiar with her, outside of her aggression towards popular acts online.

(Not that this discredits her opinion at all-- it may be merely a coincidence that every time she gets my attention, it's due to a new Twitter beef with a popular musician instead of for her own music. I read the news more than I seek out contemporary new acts. Just asking whether she's popular for her artistic accomplishment, or if she's more popular for stuff like this.)
