iphone SE plays music I don't own

I have an iPhone SE 2020 with iOS 14.4.2. When I use the Music app, the app plays the album or playlist I select (music tracks that I own), but then after it's run through the selection, it starts playing music I don't own or recognize. Usually the tracks are similar to the ones I just played, but I don't know where the Music app is getting them from. I'd like the app to simply stop playing after it's finished the selected album or playlist. I don't know how to turn off this "feature" that's bringing in and playing random new tracks based on my selection.

Thanks in advance for any insights or suggestions!
