YajanaRao/Serenity — reverse-engineered prompt

Build me a free Android audio app called Serenity for people who want one place for music, meditation, and podcasts.

I want users to be able to play audio from their phone library and from online sources, browse by genre, search for songs, and make their own playlists. The player should have a normal now playing screen, play and pause controls, next and previous, a queue they can manage, and a simple way to save tracks into playlists.

Please also add YouTube music search and the ability to play tracks from YouTube playlists if possible. I’d like a radio mode that can automatically add similar tracks to the queue, plus voice search so someone can ask for a song without typing.

Keep the design calm and clean, with a meditation style feel, not too crowded. Make it usable as an early version, but structure it so it can grow later. Look up current docs online if you need to.
