The original poster requested that I've been listening to the albums listed for at least five years... well, how about forty years for at least two of them.
Iron Butterfly's Metamorphosis, Nilsson's A Little Touch of Schmilsson in the Night, and Scheherazade conducted by Lorin Maazel have all been regulars, and, at times, all three of them have been played almost every day.
The one of these three that has been played the most over the past ten years is the Nilsson album. I have owned the first two in both Vinyl LP and CD formats for almost as long as they have been released in their respective formats; the Maazel/ Scheherazade has not been available on CD in the USA, and only recently did I find that it was available in Europe, so I ordered a copy from Amazon UK. All of these are excellent sounding, but I feel closest to the Nilsson.
