The users on MSNBC and CNN were not referring to callers. They use this all the time to go on to a clip or other news item, even when no sound is involved. I believe it is grammatically incorrect. You can take a look, yes, but I don’t agree you can take a listen. If they meant “we are all going to take a minute to listen to what is being said.”, then why don’t they just say that? Or just simply “let’s listen”?

Listen, while usually a verb, can also be a noun. We can “look” but we can also “take a look”. We “sniff” but we also could “take a sniff”. In the same manner, one can both “listen”, “have a listen”, “take a listen”, and so on.

I stand corrected. You actually can learn something on YA.
