So do these CR(R)'s have the MCPS logo?

If they don't need it, then they don't need to be CDR's! If they don't have it, then they had better not contain any copyrighted arrangements.

Avoiding paying royalites may only be a civil matter, but I am sure that if MPCS thought they were being deprived of substantial sums, they might take action. If they find just ONE CDR, they might well ask how many more might have been sold...

(And remember - what they got Al Capone for was tax evasion)
