Add YouTube Music integration

The ability to play our own music during workouts is a basic expectation from a modern smart gym system—especially one with a built-in speaker system and multimedia display. Right now, we’re limited to Speediance’s preset playlists and Apple. While Spotify integration is being discussed, please also consider integrating YouTube Music, which is the preferred streaming service for a large number of Android and Google ecosystem users. Adding support for YouTube Music would: Expand access to custom playlists and background audio for workouts Create a unified experience for users already using YouTube Music for cardio, mobility, or warmups Complement planned integrations with Apple and Spotify At a minimum, allowing Bluetooth audio playback from phones would be an acceptable short-term workaround (I understand this is on the roadmap). But full native YouTube Music integration—with playlist access from the Speediance interface—would be ideal.
