Thank you very much for releasing this!
Saw a track of yours listed on Pixabay, but only 'Unknown Realm' was featured as CC0. Glad you linked your itch packs on your website!
I always try to find the creative's explicitly stated licence.
All the stuff I release is effectively cc0. I think the copyright situation turns into madness sometimes. you can use what I release for what you want without restriction. I hope it is helpful or useful.
