hello! resident music nerd here. i don't have a lot of experience with this particular niche, but when there's a genre rabbithole i wanna go down, there are two places i turn to:
* rateyourmusic. the community's a little pretentious and it does well to not pay attention to fan ratings of things... but it's got some of the most in-depth genre tags out there. a lot better than whatever spotify's doing with genres now, that's for sure.
* if i end up being so fortunate as to find a genre i really like, i go to ol' reliable youtube dot com for dj mixes!
i ended up poking around on the tail end of the 90s in rym's city pop tag--and ended up finding a bunch of other genres you might wanna check out :}
- synth funk
- new jack swing
- techno kayo
happy exploring!
