The music box playlist player using the default skin works perfectly for any user logged in regardless of role. However, when a guest visits a page with "music box", only a list of track titles are displayed (not the player). I've searched for guest permissions or any other setting to allow the music box player to be visible/functional to guest visitors.
There is an example of this at http://bd.summit.net/blog/short-biggie/
Thank you for assistance.
