Define the Music class by adding the firmware_version class attribute. Define the initializer method and pre-populate the tracklist with the Spirit in the sky, Starman, and Escape songs. Make sure the music track's store is private. Define the play method, which sets the current_track attribute to the first item in the track's list. Define the list_tracks method, which returns the list of tracks in the Music class. Add the update_firmware method, which checks for whether the new version being provided is more recent than the current firmware version before updating.
