No distinction is made here for the various releases and most command the same price. In a perfect world everything would have it's own niche. Soon, there would be so many styles no one could possibly describe them let alone catalog them. Some groups like the Beatles, Pink Floyd, Led Zeppelin or Tangerine Dream don't really fit a catagory, they define it. Psychedelic Rap Comments are welcome.
Constructive corrections are also welcome.
However, flames are not. Don't waste my time. After more than twenty years writing price guides and music reviews, I still have a few feelings left. Rants, raves or other nasty behaviour is best left to your psychiatrist. Mine sayeth the Lord'.
