Bests & Worsts Reviews from Amazon

This is not addressed to any particular cd, but to the woeful ignorance of Amazon.com in regard to classical music, particularly classical vocal music. My case lies in your "listen to" features that are supposed,I would assume, to allow a propective buyer to hear THE VOCALIST. What whoever manages thess things obviously does know or care about is that most classical vocals (arias, cantatas, songs etc.) have long orchestral introductions, so that your exceedingly generous 30 seconds of music often does not allow one to hear the VOCALIST!!! If you do desire to sell classical vocal cds, why don't you do the smart thing and select that 30 seconds somewhere within the piece, so that one might more readily hear the VOCALIST and not 30 seconds of intro music. I doubt very much that you will listen to or act upon my suggestions as there is nothing more stubborn or resistant to change as stupidity.
