State table tried to stop music title 'string', which it never started
The state table tried to stop the music title, but that tune is not currently playing. Either the music player is not working properly or has terminated abnormally, or your state table has issued a Juke_box_stop_music when the tune did not start playing.
Check that the music tune started correctly, and that the state table checks the return status of the start request. The state table should not try to stop any tune playing that it didn’t start. Check that the parameters passed on the stop request are correct, and exactly match those passed on the start request.
