Build me an Android music player app called Convx that streams from YouTube Music and feels super polished, calm, and premium.

I want the whole app to have that iOS inspired Liquid Glass look, with real frosted blur, soft refraction, and bouncy springy motion throughout the interface. It should include the main music player flows like home, search, library, now playing, queue, album and artist pages, settings, and a lyrics screen with synced karaoke style highlighting. Make it support background playback, lock screen controls, downloads for offline listening, an equalizer, and a simple updater inside the app.

Please keep it modern and clean, and make it work well on phones and tablets. Use current Android and YouTube Music related docs online if you need to, and focus on making the experience feel smooth, fast, and beautiful rather than cluttered.
