How can I get in touch with the editor at Apple Music?

Marital,

Contact Apple via the direct link for artists:

Unfortunately it is not just uploading a song to Apple Music. You will need to create an Artist account as well as hire a distributor to handle licensing and distribution, Metadata, and royalty payments. You can view the process to do that here as well as a wealth of other information.
