Hi,
I was maded everyting as you said.
(kindly, check please attachement)

Still haven't player.

this is not the right order. you need order by the LEFT column (ordering), not by ID.
and it has to be last of all plugins. last on the list. not just the music plugins.

also, for the jwplayer, make sure in Music Colleciton configuration you have set the permissions to users are able to play songs online.

Ok.. i was try to made it last.
System can't allow me to put it as last. look at attachament

I'v maded allow to use player - now it's shown but can't play.

It's all clear. And works like a charm!
Player is great!
