Been working on and off on a Spotify recommendation egnine after getting tired of Spotify’s repetitive recommendations.

You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.

It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created. If you don't follow much or any artists, then you should enable that in order for the service to be useful, as right now that's the only pools of artists the recommendations are based on.

This is really cool! Is the underlying tech tied heavily to Spotify? I'm a YouTube Music user and would love to use a service like this

Thank you!

Some parts are, but easily abstractable. I do have it on my list to support other services, but haven't had much time lately to tackle new features.
