In my case I imported my Rdio history so it’s possible that something went wrong with a difference between loading albums & seeding the recommendation engine. It was really weird because I was expecting better based on most of the other users I knew.

The import could have something to do with it. When I started using Spotify I used a playlist importer that included many false positives when it couldn't find a particular song. I ended up with a bunch of live David Bowie recordings that I've never heard in there, and now it still thinks I want to hear him every time I shuffle my liked songs. It could have chosen a worse artist, but I don't need to hear him every time.

Talking about Discover Weekly playlist: I think the recommendation engine is mostly based on what you actually listen to. When I listen for a week to emo rap, I get emo rap recommended in the next one.

I think song/album radio is not exactly based on your taste, but on what spotify considers similar.

Try making a playlist with your favorite songs and press "enhance" or "playlist radio" to see recommendations based on that context.

I used it for a couple of months and it never got better. I ended up switching to Apple Music but I would hope that they've fixed it by now.
