Hi Tom,
Well, this is going to be a really tough one. Unfortunately I can’t promise anything, as this is a very special case of combining multiple stuff together.
Generally I would recommend avoiding live reloading of the whole site contents where possible, I guess in this case it’s not because of the music player.
I believe the issue is related to the results shortcode here. What I noticed is that for some reason it is completely cleared from the content area and the plugin is not able to push it back.
Can you try using on the simple plugin shortcode to see how that acts?
