Does Clear Channel Communications (the radio corporation) censor songs about drugs?

Question

I grew up in the heyday of FM when songs about drugs were a frequent part of the radio -- Boston "Smokin," Skynard, "The Needle and the Spoon," Steely Dan, "Kid Charlemagne," etc. I don't hear these much anymore, or other explicit lyrical content on the "classic rock" stations. Does Clear Channel Communications censor songs about drugs?

Answer 1

Clear Channel and Walmart are both EVIL corporations, both are pro censorship.

Answer 2

They're not explicitly censored; for one thing, contrary to common perceptions, Clear Channel does not directly manage the play lists of every station.  However, they do have lists of 'not recommended' songs; this does not mean explicitly prohibited, but given the trepidation of your typical corporate drone, the effect is similar.  Clear Channel *does* have a standing policy of editing out explicit drug references in songs played on its stations; this might make certain pieces sound so odd, nobody wants to listen to them.
