Tom2001moT/Echo-Music — reverse-engineered prompt

Build me a polished Android music app called Echo Music that feels modern and easy to use, based on what is already in this repo. I want a real everyday player with a clean home screen, search, library, and now playing view. It should stream from YouTube Music without ads, support background play, let people switch between audio and video, and download songs, albums, and playlists for offline listening with a proper download manager.

Please include synced lyrics, including word by word style when available, plus lyric translation. I also want song recognition like Echo Find, smart recommendations, smarter queueing, Spotify playlist import, listen together, podcast support, and local music file playback. Add useful extras like sharing song links, setting songs as ringtones, crossfade, pause on mute, resume when Bluetooth reconnects, and settings to tweak density, album art, and hide video content or Shorts.

Make it feel premium and intuitive like the screenshots, and get it building cleanly into an installable APK. Keep optional services optional. Look up current docs online if you need to.
