Query: The 10 CD 30th Anniversary Collection is a better choice.

I don't really disagree with the other reviewers' evaluation of Piaf. She is truly one of the great artists of the 20th Century. I got this set; and then I got the 10 CD 30th Anniversary Collection. This 2 CD set has only a few songs recorded in the late 50's and early 60's when recording technology could do justice to her voice. The 10 CD set has several CD's recorded toward the end of her career. The recorded sound is outstanding; and Piaf was still in great voice nearly 'til the end. I know the 10 CD is expensive; but I prefer it above anything else I have by Piaf.
