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.
