Hi! I see you’re having trouble with your songs not loading in the Demus app on your Mac. I’d love to help you get back to your music quickly. To start, could you tell me if you see any error messages when you try to play songs? Also, have you tried restarting the app or your computer yet?

Meanwhile, here are some steps we can try that often fix this kind of problem:

1. Restart the Demus app: Quit the app completely, then open it again. This clears temporary glitches.

2. Check your internet connection: Make sure your Mac is connected to Wi-Fi or Ethernet and the connection is stable since Demus streams music.

3. Log out and log back in: Sometimes re-authenticating your account helps if there’s an account or sync issue.

4. Clear app cache/data (if possible on Mac): Though less common on Mac, if Demus has cache or temporary files, clearing them can fix loading issues.

5. Reinstall the Demus app: Uninstall the app, then download and install the latest version from the official site or Mac App Store. This removes corrupted files that might block playback.

Since you’re on macOS Catalina (10.15.7), incompatibility is less likely, but ensuring the app is up to date helps.

If you've already tried any of these, please let me know which ones so I can guide you to the next solution!

Are you satisfied with this initial plan, or would you like me to walk you through any step?
