Song licensing is the process of obtaining permission to use a piece of music in various media, such as films, commercials, or video games. This permission is typically granted by the copyright owner, which can be the songwriter, music publisher, or record label. Licensing ensures that creators are compensated for their work and that users can legally incorporate music into their projects. There are different types of licenses, including mechanical licenses for reproducing music and sync licenses for pairing music with visual content. Each license has specific terms and fees, depending on how the music will be used and the popularity of the song.
