Overall, awesome job taking on a tough task. While I would certainly quibble on the placement of many, I think your "divisions" are fairly accurate. That said, your take on Alpine1:

"The X Factor: Even though the set has no true highs outside of the “Rock and Roll” > “Piper,” it also has no lulls.

What about the Golden Age from Alpine1?? I thought it was excellent, with a very groovy/funky, extended take on it, and into a very funky, albeit perfunctory, 2001.
