fast4x/RiMusic — reverse-engineered prompt

Build me a multilingual music streaming app called RiMusic that works on mobile and desktop, with a polished modern player and lots of personalization. I want people to be able to browse music, moods, genres, and new releases from favorite artists, play tracks smoothly, see synced or unsynced lyrics, and customize the look with themes and even a classic style option. Please include listening stats, playlist import and export with easy sharing, a sleep timer, and player controls like speed, pitch, volume, normalization, and skip silence.

I also want a visualizer on the player with multiple effects, but make microphone access optional and clearly explained in settings. Add support where it makes sense for Android Auto, Android TV, widgets, and video playback. A big requirement is privacy, the app should not collect user data. Make the app feel clean, fast, and easy to translate into many languages. If you need details, look up current docs online and wire up whatever is needed to get a working build.
