Hello PrinceEros,
We understand that when you'e using Apple Music it turns black.
Based on the screenshot, it looks like Dark Mode is being used. You can learn more about that and see how to turn it off here: Use Dark Mode on your iPhone and iPad - Apple Support
If Dark Mode isn't turned on and it isn't set to turn on automatically, we'd like to provide you with a few steps that can help when an app is not working as expected:
1. "Close and reopen the app
Force the app to close. Then open the app to see if it works as expected.
2. Restart your device
Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.
3. Check for updates
To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.
4. Delete the app, then redownload it
Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed."

Best wishes.
