NotchStar shows whatever app reports its playback to the macOS Now Playing service, the system service that tracks what is playing on the Mac. Music and Spotify are covered twice: through that service and, if it fails, through AppleScript. Other apps appear only if they report to the system.

Apps that work

Apple Music and Spotify. NotchStar reads them through the system service first and, if that fails, through AppleScript.
Other players that report to the system. If the app reports its playback to macOS, NotchStar can read it. Whether a browser tab appears depends on the browser and on the site reporting to the system.

Apps that may not

An app that does not report a bundle identifier to the system will not appear. The AppleScript fallback is built for Music and Spotify only, so it will not rescue anything else.

A simple test

Start playing in the app and open the Home tab. If the track shows, the app reports to the system. If it does not, and the app is not Music or Spotify, NotchStar has no other way to read it.

If Spotify is the problem, read Spotify not showing. For Apple Music, read Apple Music behaviour. The mechanism is in how notch apps read now playing. The tool is on the Now Playing page.

Quick answers.

Does it work with YouTube Music in a browser?

It can if the browser reports the track to macOS Now Playing. There is no fallback for browsers, so if it does not appear, nothing else will show it.
