Theme music in collections

[Broc0liRab3 5]

i just finally converted all my old legacy boxsets to the new way of making collections. everything works great. i figured by putting the theme music in the appdata portion of the collections folder it would play.

 

my question is how do i get the music to keep playing when i go to a movie IN the collection?

Each item within a Collection is independent of the Collection.  So every item would have its own theme music.
