Events are the preferred solution, but from anywhere in an app, including swfs loaded using SWFLoader, you can access any public member in the main application scope doing:
Import mx.core.Application; Then: var myVar:String = Application.application.publicStringVarInMainApp; //works for public functions and components too. I typically create a var, _app:Application, to shorten the code. If you type _app to the exact class (file name) of the main app, you will get the benefits of code hinting in FB.

I thin k you either have a class missing, or the wrong push button class. The button gets pressed and should fire off an event. In your application there needs to be a class that responds to the pushbutton. That class is also aware of the list, so it can know the button is pressed then access the current item on the list and activate the playing. A method of this application class can be called by the buttons click handler.. Paul
