Previews, or watermarked versions, cannot be published in any projects. A sync license is required to use any version of the song in any video project.
A watermarked preview can be used in the editing/approval process before you finalize a project, but publishing any project without a license is strictly prohibited and considered copyright infringement. Once a license is acquired, you will then be given access to the unwatermarked version of the song.
If you have any additional questions about previews and watermarked versions, please contact us for more information.
