# Sandbox.MusicComponent

Plays background music through [Sandbox.Game.Music](/api/Sandbox.Game.Music). Drop it in, pick a track. Only one track plays
at a time, so enabling another music component crossfades to it. Music isn't tied to the scene - to keep
a track going across scene loads either put this on a DontDestroyOnLoad object or turn off StopOnDisable.
