MythicalSHUB/SpatialFlow ? reverse-engineered prompt

Build me a modern Android music player called SpatialFlow.

I want it to feel fast, polished, and immersive, with a clean Material 3 look that changes colors based on the album art. It should play both local music on the device and online tracks, with a single queue that can mix both together. Include solid playback controls, background playback, and a nice now playing screen with smooth animations.

Please add audio extras like volume normalization, crossfade, equalizer controls, bass boost, loudness enhancement, and reverb. I also want synced lyrics, including karaoke style word by word highlighting when possible. Make the app support dark mode, dynamic theming, and a lightweight feel.

Use current Android best practices, and if you need to look up anything in the latest docs online, go ahead. Make it work well on modern Android phones and keep the interface elegant and responsive.
