I remain appreciative of your recommendations regarding music. So you should know, I am not completely blind in this regard. I have at my disposal the following, in optical format, and I tend to use the following.
1) Sportin Life (all tracks) by Weather Report. This disk was used in the 80's by Leonard Radio (Manhattan NY) to demo all their equipment at the time. They sold rather high-end and pricey items. https://en.wikipedia.org/wiki/Sportin%27_Life_(Weather_Report_album)
2) Denon Audio Technical CD. It has a number of tracks with sample music that covers the entire gamut of frequency range, dynamic range, imaging subtleties, etc. http://www.cduniverse.com/search/xx/music/pid/1526639/a/denon+audio+technical+cd.htm
3) Sony Music Super Audio CD Sampler http://www.amazon.com/Music-Super-Audio-Sampler-Players/dp/B003UQ4CXC
