"Rolling Stone" ranked "Imagine" number three on its list of "The 500 Greatest Songs of All Time", describing it as "an enduring hymn of solace and promise that has carried us through extreme grief, from the shock of Lennon's own death in 1980 to the unspeakable horror of September 11th. It is now impossible to imagine a world without 'Imagine', and we need it more than he ever dreamed." Despite that sentiment, Clear Channel Communications (now known today as iHeartMedia) included the song on its &lt;a href="2001%20Clear%20Channel%20memorandum"&gt;post-9/11 "do not play" list&lt;/a&gt;.
