A unified Android music app that integrates YouTube/YouTube Music streaming with one-tap downloading to local storage, automatic metadata fetching (album art, artist info, synced lyrics), and a polished Material You player interface. The app would handle the entire workflow from discovery to organized offline library without requiring multiple tools or manual tagging.

Streaming subscription fatigue is driving users toward owned music libraries, while YouTube Music's vast catalog (including rare remixes and removed songs) provides a comprehensive source. Material You design language maturity and improved metadata APIs^? make building a polished, automated solution more feasible than ever.
