Is there any curation system that actually works well? Fucking hate the Spotify forced recommended categories blended with random maybe poorly recommended things to listen to. Apple music playlist just sucks for me too now.
Personally? I find Youtube/YTMusic scarily accurate at maintaining "coherency" between tracks. I could listen to a 1 hour (human made) mix and I won't realize when the mix ends and the algo picks up. Spotify (for me) mixes upbeat tracks onto slow songs and mixes instrumental tracks with vocals and whatnot. Youtube rarely misses for me.
The best I guess is last.fm, which works based on "you like A, lots of people who listen to A, listen to B and C as well. Give it a try?" But honestly, nothing beats exploration and putting some work into finding yourself. I like to read comments in YouTube and last.fm.
YouTube music worked for me, after a while, and that while was months. Another one is Mixcloud, where if I find a DJ, or radio personality whom I find interesting music-wise, I can listen to their long mixes to see what they come up with. Mixcloud is a bit more human, I feel. It also has a free tier, I used it like that for years. No account needed to try either, just go there and explore.
Ugh.
