I have 2 cd's on the Hollywood label,
Classic Queen and Greatest hits. The recording quality of both of them is very good, most sound excellent. The 'Seven Seas of Rhye' is not the best mastered song on the 17 track 'hits' cd.
It is very listenable though as all the other tracks are, with the exception of wtf 'body Language'?! got to be the worst Queen track ever, but sounds really good, only listened once I might add (maybe twice).....
The cd's were mastered by Eddy Schreyer. Is it him that did the mastering on the vinyl also? I have most of the early pre cd stuff on original vinyl by Queen, but have not played the albums for many a year, hence why I bought the cd's.
Sorry I could not help you with your question, I hope somebody does.
