Teach the world to 'chill'?

"I'd like to teach the world to chill, take time to stop and smile / I'd like to buy the world a Coke and chill with it awhile."

I heard these lyrics tonight during an advertisement prior to a movie. I shall save the rant about advertisements before movies, which I paid to enter, at another time. For the time being, though, I'd like to stand up and say I'm sick of the whole retro movement, especially if they're going to ruin it for the benefit of promoting something called "Coke Zero," which is roughly the amount of interest I have in this product.

Obviously these lyrics harken back to the "Hilltop" scene Coke made famous in 1971. It came at a time when the world had some unifying to do, and it involved people who looked vastly different, standing next to each other. They sang about wanting to teach the world to sing and live in perfect harmony in a time that was less than harmonious.

Now they're talking about the need to "chill," which, as far as I understand it, means doing absolutely nothing and being happy about it. I'm not against chilling, but I do hate it when we try so hard to harken back to something from a previous generation that we'll rewrite perfectly good songs. What happened to original thoughts?

Of course, since I'm ripping on original thoughts, I might as well rip on myself. I found the following other bloggers who wanted to talk about the Coke chill maneuver:
Philadelphia: Teach the World to Sing
Teaching the World to Sing
G-Love Teaches the World to Chill
Adland
Partially True Adventures of High Adventure

I suppose you get the idea. Now it's time for me to chill, man. Teaching the world to sing in perfect harmony is so 70s. I need my me time.
