- Written in C
- Can manage large music libraries of over 10,000 music files without issue
- Compatibility with MusicControlol Decky plugin; play music while playing games!
Every gamepad action has a keyboard twin so Steam Input can bind buttons to keys. The same list is in Library → Settings → Controls. The Steam/Guide button is unbound (Big Picture / on-screen keyboard).

Preset lock, Shuffle, and Repeat sit on the now-playing extras row (Up from the seek bar, then A). The current visualization name is on the right of that row; A opens the full preset list. Search uses a QWERTY grid plus Clear/Backspace; Steam’s keyboard also types into the field.
Hold A on an artist, album, playlist, or radio station to add or remove a favorite.
Hold Y on a song, album, artist, folder, or playlist to append it to the queue.
Hold X removes a song that is already in the queue, from the queue screen or from
the list you added it from. Search is Library → Search. Queue → Queue Options can
clear the queue or save it as an .m3u in your music folder.
B on Library goes back to now playing. On now playing, B hides the HUD; B
again asks whether to quit. Tab and Esc both open and close the Library.
