Spotify keeps playing thundercat

[PJH3]

I downloaded a thundercat playlist and didn't like it. I deleted the playlist. I unfollowed thundercat. No matter what I do it only plays thundercat.

It no longer only plays thundercat. However, if I play my favorite song list, or any other playlist, it will play the first song on the list, and then only plays songs that I have never played before.
