I am hoping for some direction on the legality of using copyrighted music with photo slideshows. We want to be able to provide our clients with slideshows of their wedding, using their wedding song as the background music. I am not sure how to go about that legally. Do I need a license from the artist and/or lable company, do I need to pay a royalty fee for each slideshow sold, etc.? I want to keep my business legal, but I also think this is a product that we should be able to provide! Please help!
