Who Me Too'd this topic

I have had Spotify Premium for a number of months without issue, (aside from the rubbish shuffle). The last week or so songs from an artist by the name of Lee Tu Nguyen will randomly start playing, even though none of the songs played are on any of my playlists. Indeed, I have never even heard of Lee Tu Nguyen before it started playing randomly on my Spotify.

This will happen in two ways.

1. I will be playing through a playlist and half way through a song the playback will stop and it will swap to Lee Tu Nguyen.

2. I will not have touched the computer at all and Spotify will randomly starting playing Lee Tu Nguyen songs without my permission.

Methods I have tried to fix this problem:

1. I have logged all instances out with the "Sign out everywhere" button in my account settings.

2. I have reinstalled Spotify.

3. Removed all offline devices.

4. Revoked access for all apps.

What in the world is going on? I don't pay for premium to be randomly woken up during the night with some annoying artist I have never heard of, nor do I pay to have my listening experience interupted by, (again), some annoying artist I have never heard of.
