.. all great material and very interesting to read, the only artist I generally question on a list dedicated to the 60`s is the high placement of the Velvet Underground as they did not exist in the 60`s based on the criteria (Equal parts Commercial Impact, Influence, Musical Impact and Cultural Impact) until the 70`s and generally only after some interest in Lou Reed`s solo material had developed. The VU would not have moved more than 10,000 units of all their material during the entire decade of the 60`s, there is no mention of them in any music and trade publication outside of the general New York area in the 60`s and their music was not played or distributed in any significant way beyond that geographical area and I am not sure if there is any material of any artist in the 60`s stating any influence to the VU (years after yes, but not quoted in the 60`s as far as I have ever seen)....
True, if this list was made on 1/1/70 the Velvet Underground would not have made it at all.
There seems to be a common misperception of how the influence criteria is applied. Influence means whatever work done IN the 60's that was later influential. It does not have to be influential on other work within the same decade, so for VU that influence became noticeable years later, decades later even, and that's the reason why they get their spot - massive influence. Ironically, more people say they're too low here rather than too high, but it's good that you were looking at it from a criteria-based standpoint. Hope that clears it up.
