the smallest thing is ICO about music, indeed I am not sure if music enters crypto, not disagree, but it is very unlikely that their ICO will succeed, project that now runs on music is Soundeon. the ICO income they get, you can see for yourself on the ICO website
Blockchain in music is a good tool for copyright. In the US and the EU are very strict with this, so prospects there are many such projects.
Yes, I agree with you. In Russia, it would be useful to follow the example of the US and the EU in this matter. Yandex is certainly trying to develop in the direction of improving copyright security, but no one else is doing this.
