Music publishing administration refers to the business of collecting money for the music that you write. When music is used commercially, the songwriter and copyright owner is owed royalties.
This is a different royalty paid for the distribution of a sound recording which is an entirely separate copyright and income stream.
Under an Administration Deal, the songwriter retains 100% ownership and complete control of their compositions. As a music Publishing Administrator, TuneCore Publishing Administration administers your compositions by licensing, registering and collecting royalties on behalf of your compositions, ensuring you are not leaving any money on the table. This is an additional revenue source to the revenue TuneCore is already paying you from the distribution of your records.
