Random downloaded songs in Apple Music storage but not in my library or downloads

I went to go check my storage in settings, and when I got to the Apple Music storage, there was a bunch of random downloaded songs that I’ve never heard of or listened to. When I went to the music app, the songs weren’t even in my library or shown in my downloads in the app. How does this happen? Should I be worried about security? I have automatic downloads turned off.
