Searching Spotify for user created playlists is still probably your best bet. Youtube has some good results too.

Here are two that might fit what you're looking for:

'90s K-pop: https://open.spotify.com/playlist/6mnmq7HC68SVXcW710LsG0?si=...

'00s minimal techno: https://open.spotify.com/playlist/6mnmq7HC68SVXcW710LsG0?si=...

There are sites to convert from spotify to another service if you don't have it.
