I'm not sure about "girl pop" concert vibe, but i don't see much video pointing out at people in the crowd in concerts (in fact, i only remember one, and it's not really being mean at the person). Also there may be some kind of survivor paradox here : the video you see of young adult woman may not be a realistic depiction of the crowd, there probably is people just chilling, but they're less interesting to film, so there's less video about them. I'd say enjoy yourself !
