I waive all responsibility for any child conceived after watching this video.

A group calling themselves "cdza" (short for "collective cadenza") is composed of graduates from the prestigious Julliard School in New York City and spends their time creating what they call, "musical video experiments" for their website and their YouTube channel. Their first video, called "History of Lyrics That Aren't Lyrics" was created a little less than a year ago and is nothing more than an ode to several of the more famous, "Na-Na-Na's", "Whoa-a-Whoa's", and "La-La-La's" in music history.

Their most recent entry, "History of Wooing Women" was posted to their YouTube channel today and chronicles the evolution of the love song from 1955 through 2010.

Obviously they left out several newer, "true love songs", but if you didn't catch on by watching the video, the idea is to exaggerate the idea of how the topic of love and sex has changed, for better or worse over the years. Clearly the innuendo of the past has been pushed to the side in favor of the more blunt approach taken by many of today's artists. Whether that's good or bad is up to you to decide.
