A more thorough explanation:

A blanket license is a type of license that allows the licensee to use a group of copyrighted works without having to obtain individual licenses for each work. This type of license is often used in industries such as music, where a radio station or streaming service may want to play multiple songs from different artists.

A radio station obtains a blanket license from a music licensing organization, such as ASCAP or BMI. This license allows the station to play any song in the organization's catalog without having to negotiate individual licenses with each artist or their record label.

Another example is a blanket license for software. A company may purchase a blanket license for a particular software program, allowing all employees to use the program without having to purchase individual licenses for each user.

These examples illustrate how a blanket license simplifies the process of obtaining permission to use multiple copyrighted works, saving time and money for the licensee.
