I'm making a soundtrack for a film, but instead of writing the music, I'm buying songs from music libraries and building the score. In other words, except of actual writing the music, I'm doing the whole soundtrack from scratch - including planning a concept for the music, setting the right tone, finding the pieces of music for every part of the film and manipulating them to fit the needs of the scenes. My question is, what credit should I get for this work?
Thanks
