Willow, I'm a fan of 70's British Rock and Roll, look at the other names, there's a pattern.
I'd have given Status Quo, Slade, T-Rex and Cheap Trick a run before 2/3 of the crap on that list.
Bronco, I was on the phone to my girlfriend this afternoon trying to work out some of the 20 songs left to go, hence #15 - #18. She was pretty flummoxed by Tool's non appearance too, they are definately a brilliant band. I've got 2 of their Albums (one taped by her) and although they are an acquired taste for someone of my vintage, I have to agree with her and yourself.
To whoever gives a stuff, I hate that don't think song. It blows Goats.
The only good thing about that list is they saw fit to not class anything by Savage Garden as Rock.
