ZenMusic brings JioSaavn, YouTube Music and Spotify into one clean, fast player, so you don't have to switch apps. Standout features: synced lyrics that follow the song, Listen Together to sync playback with friends, offline downloads, song recognition, and customizable player skins and layouts. Free, GPL-3.0, and built with Flutter for Android and Windows. Still in active development, and user feedback shapes what gets built next.
