Hi there Redmoonlight22,
Thanks for letting us know. Another step you can take with your iPhone 11 is to restart your iPhone. This will refresh the iOS and also the Music app, which may stop this from happening. If needed, below shows how:
"How to restart your iPhone X, 11, 12, 13, or later
- Press and hold either volume button and the side button until the power-off slider appears.
- Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
- To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."
Those steps are from this article: Restart your iPhone - Apple Support
Another step you can also try if a restart doesn't help, is if the songs or albums you are trying to play are in your library, you can remove those and add back to your library and try again. If needed, this article can help walk you through that: Add and download music from Apple Music - Apple Support
Please let us know how those steps go or if you've already tried those.
Take care!
