You need a license to use music if the AI-generated music is based on copyrighted works or reproduces protected music content or parts of it. The safest option is to purchase a license for music use. 

By obtaining a license, you ensure that your use of music is lawful and that music professionals receive appropriate compensation for the use of their works. At the same time, you gain the right to use music without having to worry about how it was produced. On our licencing page, you’ll find licenses for various types of use.
