The issue is you're claiming three incompatible things
- 'no copyright'
- 'CC0'
- 'you just can't sell the music as it is'
It is not possible that all of these things are true at the same time.
For example by claiming CC0 you have waived 'all of [your] rights to the work worldwide under copyright law', but then you try to assert the right to tell me not to sell them? How do you think this works?
