Why on an iOS Phonegap build when I play it, and I bring up the tray bar as Im playing I can see in the player the current bg music of my game, it shows in the title something like "file:///private/var/mobile/Containers/Bundle/application/ADBC-6CA7-..../myGame.app/www/media/nameofthesong.m4a"
And I can even pause it and fast forward it.
