God knows. I guess you would have to contact the author to get that info. Clearly, the emphasis was on the English-speaking World, as we are dealing with English-language pop music and other styles of music here. We are not dealing with Russian or Indian music or Latin music, for example.

I would think the majority of votes came from the USA, and the UK. Secondarily, from Canada and Australia.

The fact that Gordon Lightfoot does not get even a mention in the book is extraordinary. He only wrote about 600 great songs! Ian and Sylvia also get no mention, nor does Buffy Sainte-Marie. They are all Canadians, and all folk musicians. Kate and Anna McGarrigle DO get a mention, for their debut album, however. (and they were not nearly as big a factor in folk as Lightfoot, the Tysons, and Buffy...but they WERE very good, nonetheless.)

The 60's seems overly heavy to you? What's your age? It's the 70's that rates the most albums on the list, not the 60's. What seems to me to be overemphasized in the list is the 90's. It all depends on what you are familiar with, that's all.

I wasn't asked either! :-)
