Your artist retains 100% ownership of the master and composition of your song. With your song purchase, you are granted a Personal Use License. What that means is you can share your song, post it on your personal social media channels, add it to personal videos/slideshows, etc. As long as it's for personal use and is not promoting a business or product/you are not monetizing your song, you're good.
If you have specific use questions, please reach out to our Customer Success team HERE and they will be happy to help!
