I want to build a music player that uses YouTube Music as its backend. The main goal is to create a free, ad-free listening experience that allows background playback on Android but also works as a desktop app for Windows, Mac, and Linux.

It should have a polished, premium feel. Let's include features from other popular apps, like Spotify's Canvas visuals and synced lyrics. It also needs to integrate tools like SponsorBlock to skip intros and sponsored segments, and also show dislike counts on videos again. Key player features should include high-quality audio streaming, offline playback through caching, artist notifications, and support for Android Auto. For social features, it would be cool to have Discord Rich Presence support so friends can see what I'm listening to. Make it feel like a super-powered client that combines the best of everything.
