what other streaming service do you think has a better algo? Spotify is leagues above AM, Deezer, Qobuz, etc.

Bandcamp and RYM.

I wasn't thinking of streaming services, but communities and websites. Also, Bandcamp (which does have streaming but I don't think of it as that primarily)

Any tips?

Depends on what sort of music you're into

Punk and what ppl usually like. I thought such a recommendation engine would be quite taste agnostic anyways?
