Music featured in videos marked with [Royalty Free Music] can be used for any project, however you will have to credit me as the composer.
Other tracks are NOT royalty free. You will have to buy an additional license for using them in your project. The only exception are YouTube videos, where you can use my music for commercial as well as non commercial purposes without having to buy a license.
For a license, contact me and I will set up a contract for you.
