Where does Fleetwood Mac rank among the greatest bands?

[Nicks Fan]

What I always found interesting is that Eagles got that award around 99-2000 where they were honored for selling more albums then any othere artist (Including Elvis and The Beatles). I like the Eagles but I am amazed that given there small output of studio albums (7 in 40 odd years) and yet they sold so many. Also everytime they get back together it seems to be bigger then the last time. I like FM more simply because they have more albums and have taken risks in their music. FM unfortuantely will always be defined by Rumors even though they have made some worthy music since then.
