I’m currently producing my first feature film, which was Inspired by a song. So now that I’m producing it, I want the song to be the soundtrack. But the problem is , the song is already another movie’s soundtrack. I know I can hire someone to write something similar but I kind of want that song. Can an existing movie soundtrack be another movie’s soundtrack? The song is “ It will rain by Bruno Mars” . Please help me figure this out so I know My options.
