I was thinking of putting a song in my film, but I need to know what kind of permits or liscences you need to get to legally put a song in the film. I know that prices vary big time, but if some of you could give me links or places I can read up about or obtain liscences, that'd be great!

One man writes a novel.
One man writes a symphony.
IT IS ESSENTIAL FOR ONE MAN TO MAKE A FILM.

-Stanley Kubrick
