When purchasing a single song license or creating a license through on a subscription plan, you will be asked to enter the project details. This information is printed on the license agreement itself, and without these details clearly written on the license, the license cannot be considered valid. An invalid or incomplete license won't legally cover the use of the track in the project should any copyright issues arise.
Please note: if you have a Personal subscription that doesn’t cover client work, feel free to simply type your name or the name of your channel into the End Client field.
