I got to thinking, because the likes of Danny Elfman and Alan Silvestri were mentioned in another thread, and I know both of their work have been used outside of their respective movies.
For example, I hear Elfman's Pee-Wee score from time to time in various other things, mostly on TV and such for music montages and even commercials, meanwhile I remember when the first Harry Potter movie came out, the score from the movie Mousehunt (which Silvestri scored) was used for trailers and such.
So, is there like a legal thing that makes movie scores become part of the public domain or something?
