First off,
Your music is awesome!
Secondly, you rock for sharing it and for letting us know here that you do.
Third, is a minor nitpick in case it is of use to you (...cause that's what happens on message boards).
A bunch of companies out there offer Royalty Free music and while it turns out it is technically 'free of royalties', they still claim ownership in the music and intend to charge for its use. This is dangerous to random Youtubers as they might use the music and then get hit with a copyright violation. I.e. They never bought a licence to use it so they can be demonetized or get a strike. This kind of risk might cause people to shy away.
If what you mean to do is permit Youtubers to freely use your music without risk, might I suggest you include in the description that there is a Creative Commons Licence associated with it?
[I will be unable to post a link here, but just google Creative Commons Licences.]
You will see there are different kinds. I suspect you are after one that lets everyone freely share and use your music but they are required to attribute the music to you (as they should!).
When people see a reference to the licence in the description of the video, they are more comfortable placing the music in their videos. Perhaps something like: "This work is licensed under a Creative Commons Attribution 4.0 International Licence."
Anyways, apologies if I am telling you stuff you already know - I see you have a much more significant history here than I do.
Thanks again for posting the link and all the best with your channel!
