Hello Libsem,
Apple Music is a great service! To confirm, are you seeing any error messages when trying to download or search songs in Apple Music on your Mac, or is the Music app becoming unresponsive? If the Music app is freezing or becoming unresponsive, complete the steps listed below. These steps are specific to resolving issues with applications on your Mac. After completing a step, test to see if the issue has been resolved or continues before moving on to the next step. You can also find these steps outlined in the following article.
- "If an app doesn’t quit as expected, or it’s unresponsive, you can force quit the app (you may lose unsaved changes). Choose Apple menu

- Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of macOS.
- Uninstall any app plug-ins or enhancements from other manufacturers.

If an app freezes or quits unexpectedly on Mac - Apple Support
If the app isn't unresponsive, have you quit and reopening Music to see if the issue persists? If not, you can quit Music by clicking Music in the top menu (when the app is open), followed by Quit Music. After you've quit Music, reopen to see if the issue persists. You'll also want to make sure you're running the latest macOS. Since Music is a built-in app, any updates for Music would be included in the macOS update. You can find the steps for updating in the following article.
