Thank you for your reply. IANAL, but yes, I think your license is not CC0. CC0 is "public domain". It is intended to abandon all copyrights. So if you want to publish music under the license, you can't argue any restriction. And, Unsplash license is currently not CC0. It WAS originally CC0. I like your philosophy, so I want to agree with you, but I cannot help concerning about licensing issues on FLOSS or mix-in usages...
