So, I came up with a rolling points structure to ID the biggest all-time artists, recognizing that artists have staying power from prior years. This allowed me to create a points structure that looked each year at the artists performance over the past decade, weighted by year for recency. The artists that topped the most of those listing will be #1 here, followed by the artist who topped it for the second longest etc. There will be some surprises. And John and I will have top 100 #7s in the fall.
