The organization, Broadcast Music Inc., which collects license fees on behalf of songwriters, composers and music publishers, including Mr. Jackson, who died last Thursday at age 50, has gradually shifted the bulk of its jobs to Music Row in Nashville from West 57th Street in Manhattan, said Robbin Ahrold, a spokesman for B.M.I.
It now has about 140 jobs in the city, down from a peak of about 500, and plans to move about 110 of them into two floors of 7 World Trade Center in the spring.
