While looking for something else entirely, I noticed this on the EFDSS website:

"Members who pay for their PPL licence through EFDSS can download TheMusicLicence terms and conditions here."

I can't add a direct link to the T&Cs but it's on the group membership page:

https://www.efdss.org/support-us/join-us/groups

Typically of EFDSS, I can't see any other reference to it offering this service, why you should use it, or how to apply.
