Which band do you think is the greatest of all time?

In my opinion, Pink Floyd is the greatest. Their style is unsurpassed and I have songs from every album on my iTunes. I other words, I LOVE PINK FLOYD!

Pink Floyd is cool, but my favorite of all time is The Beatles!
?.?.THE BEATLES, THE BEATLES, THE BEATLES, THE BEATLES, THE BEATLES, THE BEATLES!!!.?.?

Kansas
They had a lot of sucess over 30 years. They continued pumping out hits their entire career also. They have a song in a Guitar Hero game, which was than played on South Park, which got kids and teens interested in them now.

And if this helps me get the best answer:
I was kidding. Pink Floyd of course.
