Depending on the arrangement you have with the library.

Most libraries won't share a blanket license, i.e., giving a client access to their entire catalog for $4-5 grand per quarter. Too difficult for the library to calculate each writer's compensation. So they say.

Some libraries will take 50% of the blanket licensing and just split the rest equally with the writers whose tracks were used. A little better. But using the $5,000 figure and 100 writers; the library would make $2,500 and each writer would earn $25.
