"Appreciate the response, but there have been no changes to my home network and have been able to stream every other service consistently and without interruption. And the Apple Music streaming has worked on other devices on the same network. It is a unique problem with the Apple Music app on the Macbook Air."

Troubleshooting Music App:
So, if this pertain to this one Mac, then it has been successfully singled out.
1. Apps Slowing your Mac:
A. Check Force Quit:
See if something is listed as "(Not Responding)". Go to: Apple Menu > Force Quit...> Select anything ending with "(Not Responding)". Also, while in Force Quit... be sure to select Finder, and Click "Relaunch"
B Remove Login items:
See if any of these apps are a Login Item. If so, remove them as such and then restart the Mac, seeing if it/they no longer load(s) at login. Go Here: Change Users & Groups Login Items Preferences on Mac - Apple Support.
2. Create New User:
For temporary use, create a new Administrator. See what happens when you log in to it. Do you still get this issue? If not, then is it a misconfiguration in the current user. If so, then you'd likely have to resinstall the macOS.
3. Reinstall the macOS:
Nothing would be lost. It's just that misplaced items would be placed back to where they should be and corrupt system files would be replaced by clean files. Go Here: Reinstall macOS - Apple Support. Use the third bulleted method: [command + r]. Important: Prior to installing an update or performing a reinstallation, to prevent data loss, be sure to Back up your Mac with Time Machine.
