I have been to a lot of concerts: what I've noticed is chris brown concerts the the skew was really heavy female (maybe 80%), as well as Doja Cat (maybe less drastic), Cardi B, SZA, Flo Millie, and Jaheim (older women, but still heavily female). All of them had a healthy (65%+) women audience.

Obviously all of them still have male fans, its not as skewed in my opinion because there is a lot of avenues for men to be brought into the orbit (gay men, the occasional straight male fan, and it cannot be understated the amount of guys that are brought in as a couple, not necessarily a massive fan).

Also this is not music, but I am a huge fan of a lot of reality TV, particularly Below Deck and RHOA and RHOP. I have gone to meetups even for certain viewings / discussions around the shows and as you can imagine it is heavily female but that shouldnt really be a surprise.
