@MAKADARK that is cool you have created something.

What I do know is that In general, there are six types of licenses that someone can use for various purposes. They are: synchronization license, mechanical license, master license, public performance license, print rights license, and theatrical license. The licenses you have should clearly tell you which you have and what its limits are.

I am not sure who you received the licenses from, but there is often an identification code associated directly to you. A common thing on most licensed music uploads I see after the musician/artist has said everything they want to in description is:
"Licensed for fair use under / by ....(who licensed it)...ID#"

The ID# may not be prevalent as some licensing authorities know who you are and only need do a database search under your name to know whether it is licensed or not. If you are using a handle or Musical name then I'd recommend the ID# not so much for viewers, but more for anyone that may choose to check if you have the right to publish it for sale.
