There is definitely a element to high energy music which appeals to younger crowds. Same reason clubs tend to turn music up to levels capable of causing hearing damage.

I even exploited this fact as a way of staying awake a couple times while taking long road trips, as a stand in for caffeine.

Having high energy music is OK, allowing it to disturb the peace is not, time to teach the lessons about manners and being considerate, I suppose (buy a pair of headphones for her, limit her volume so she doesn't suffer early onset hearing loss).

No guarantee she won't turn out to be obnoxious as an adult, but that's the genetic lottery, I'm afraid.
