Having never been an 11 year old girl in a pandemic, I can't really speak to what "normal" is. Based on the the girl's behavior as described in the article, it certainly has had no noticeable negative effects.
I'm not a conservative and grew up listening to the music others where considering bad and were on the other side of the fence, they were an outdated generation in my eyes then.
Now as I got older I realize a lot of it was just crap stuffed into our faces keeping us from discovering the real good artists out there. Those folks did have a point here and there. A lot of that music was pumped by the music industry purely to make money and similarly this addictive software is doing the same thing with amplified effects and more shamelessness.
