I like surprises like that in lists, because sometimes it inspires me to check them out. Not often, because I'm really lazy, but sometimes.
Okay seriously -- even though I was being serious before -- I just meant that if I'd never heard of Björk but totally idolized Geddy, I may say "Wow, I need to check out this Björk if Geddy really likes her". That kind of thing. Recently, Yes showed up on JP's list and Geddy's list. Right now, I imagine there are people out there who've heard of Yes but never really dug into them doing just that because hey, if both JP and Geddy think they're awesome, there's probably something to it.
