Do people find such contributions useful?>
well, since you asked: not if its the beatles. ;-) we (and by 'we' i mean me and at least 5 friends of mine) relatively younger people tend to dismiss them (the beatles) as a bit of wishful thinking on the part of the previous generation, dressing up the pop of their generation as some sort of deep art.
seriously though, i am the least qualified to comment, since my own posts, including this one, are of equally dubious merit with respect to the intent of this list!
