THEY REALLY ARE BEAUTIFUL ARIAS, but there are quite a few missing too, let's face it there is a great deal to choose from in the classics. I wish they had done it as a 3 CD set, or even 4, 5, or 6, like the "100 best of" series and that's why I gave only 4 stars, but what is here is divine, I just wanted more for my money, still highly recommended.
PS. A few tracks from 10 on the 2nd CD are different from the current mp3 samples, still good though but yet another misleading mess up from amazon and I keep telling them !!
