Thank you for this. I've tried all three samples you provided by creating a default theme.css but I'm still only getting the default green background. I've tried full refresh with ctrl +f5 and restarting the app.

It should work with the latest alpha release:

SomeFolder

+-- current-song2.exe
+-- config.toml
+-- theme.css

I made some updates, maybe your version had some bugs, try the new version.

New version works great in Win10. However, it does not work in Win11 at all. No song display shows up. Theme, no theme, exclude include... tried all.

Did you try spotify? I'd expect at least Spotify to work. You should be able to turn on debug logging by setting RUST_LOG=debug in the environment variables.
