Welcome, Tim Lovern and @All, to Apple Support Communities!
I’m sorry y’all seem to be having trouble with the Music app on Big Sur.
Unfortunately, all I can provide y’all with, at this time, is the assurance that this is, most certainly, not a fault in just the Big Sur software (which includes Music), since many of the rest of us have experienced no such troubles.
This suggests there is either a hardware or other, third-party, software interaction.
A recommended test for the third-party software possibility is to boot into Safe Mode, and try Music there, without running any third-party software.
If you have trouble in Safe Mode, without running any third-party software, this greatly narrows the possible causes.
If you have no trouble in Safe Mode, then try rebooting into normal mode, and see if the problem recurs.
Since booting into Safe Mode includes performing a repair of your filesystem (which is why it can take extended time [as much as 20 minutes] to boot into Safe Mode), there are cases where this can actually correct some issues even running normally.
