So I've been using Metrolist on Android and really like it. I know the team is already working on their own cross-platform app, but it isn't out yet, so I went ahead and built my own little macOS version in the meantime.

It's basically a lightweight desktop player for YouTube Music. You can search for songs, play them, see synced lyrics, and download tracks to listen offline. Nothing fancy, just the stuff I personally wanted on my Mac.

To be clear, this is completely unofficial and not made by the Metrolist team. All the real credit goes to them since I'm building on top of their work. Once their official app lands, that's probably the one you'll want. But until then, this might be handy if you're on a Mac.

It's free and open source. You can grab it here: 

Would love any feedback or thoughts.
