No, I don't particularly think so. And I think that's an odd statement tbh, it's so out of line with what actually goes on.
It's certainly not just teenage girls that have a thing for guys in bands.
Even with teenage girls, they are often quite keen on teen boys in bands, so hardly grooming, they are the same age. Even when it's older men, they don't need to be actually making any effort to "groom" the girls or women, in fact even if they aren't interested at all, are married etc, they will often be pursued.
They don't have to be super successful or wealthy either. One of my employees, who is a regular guy with a regular job, married, also plays in some bands. You can see women waiting for him after the gigs, they aren't there because he's going to offer some kind of financial advantages - quite the opposite, he's got a pretty working class, small town lifestyle.
