Would you mind putting a proper license on this? The Free Software Foundation has a good explanation of why “informal licenses” are bad. (TL;DR: In some countries, the law might interpret a not-precise-enough license statement as invalid and, thus, “All Rights Reserved”.)
From your “Music License” description section, it sounds like what you want is a Creative Commons Attribution license (CC-BY).
Once that’s been taken care of, I’ll happily include it in my Libre Game Assets list. (Assuming I didn’t misinterpret your intention, of course.)
(I’d include everything of yours that’s under suitable terms, but I can’t figure out how to get a complete listing of everything you released, so I’ve only started to encounter your stuff on a case-by-case basis as it turns up in searches and “you might also like” listings… something I’ve been dragging my heels on until I can find time to write something which automates the process of searching Itch for listings that are tagged with or mention recognized libre licenses.)
