Catalog financing in the music industry refers to the financial activities involved in the acquisition, sale, and investment in music catalogs. A music catalog is a collection of songs and their associated intellectual property rights, which generate revenue through royalties. Companies and investors acquire these catalogs for their stable and predictable income streams. This subcategory also encompasses various financing methods, such as leasing rights or equity financing, where creators can sell a percentage of their future royalty income for upfront capital.
