I didn't post it, but I was thinking along those same lines and even was considering starting another thread entitled "Favorite Albums" to remove the need for a specific number and that stupid "of All Time" qualifier. To me, if everyone included an album that they didn't like just because they thought it was significant, that wouldn't help me find music I didn't know about that I may
like to hear!
I didn't go forward with it (the new thread) because I realized the type/genre/classification/etc. qualifer
was needed or you really couldn't compare things well (I mean, how could you possibly compare the Beatles' Abbey Road to, say, Paul Oakenfold's Cream Fields?). It's like contrasting Muhammed Ali with Michael Jackson, Michael Jordan and Nikoli Tesla. Each is better evaluated with others in their fields or groupings.
Obviously, I've got selfish reasons for this in addition to provoking interesting conversation. If I see someone make a list with a lot of albums I also enjoy, then you can bet I'm going to check out anything on there that I haven't heard before!
