Great work! Very appreciated! Further affirmation of why I love this sight! Your data confirms some of my humble suspicions. While there are the 'likely' openers and set-closing songs, there is a concerted effort to work new song placements, and unique or rare songs. It's nice to see this data!
I wonder if anyone has done a similar analysis of 1.0? Maybe it would be more accurate break it up into two sections, maybe pre-90 and post-90. Anyhow..huge props!
Love this community!
