I get your point about the inherent problems with compiling a listing of such artists - objectifying the subjective is oh so tricky. But I don't get why in making the point you include a link to the damned list? I mean you are inviting people to peruse and comment on the list that you decry as "foolish."
Anywho - I did peruse the list, and have 2 comments to make...
1. Flaming Lips made the list - I bet they are the only ones on the list that have played at Sun Tan Lake (where I saw them circa 95?)
2. Stephen Malkmus is 79, while Kris Kristofferson is 38? Come ON PEOPLE...
