What "dead" genre of music do you wish would make a comeback?

"Dead" may be harsh but moreso, which genre is WELL PAST its heyday that you would love to see make a comeback?

-THE GENRE HAD TO OF HAD A WAVE IN MAINSTREAM POPULARITY AT SOME POINT TO BE CONSIDERED.

If you asked me this a few years ago, I would of said Pop Punk, however, throughout 2020-2021 there actually was a pretty major pop punk revival, and it SUCKED to say the least. Bunch of Blink 182 clones trying to profit off nostalgia sounds.

But surely theres other genres that were once popular that could make a return right? Honestly I wouldn't mind seeing some new age Glam-Rock / Hair metal bands start coming out.

Some may say it's not "dead" but old school Gangsta Rap is definitely past its prime and not mainstream anymore, but I'd love to see some new rappers start to blow up with that classic sound and bring that back. What else would be good?
