I cancelled spotify recently when I had a guest in my car who proceeded to play all her favorite music on my account. I wanted to remove her music from my history so spotify would hopefully not recommend her music to me but there is no way to delete your history

Account deleted. I know I'm not the norm but Spotify has never done a good job for me recommending music, ever
