Quantifying pop songs

Google and the internets are magical things. On the way back from my first tutorial today, I saw these graphs posted on someone's office door -- but, no citation as to where they got them.

However, a brief round of Googling, and I found a repository. Ooh, yeah.

Funny -- although many of them are probably generational: you gots to be of a certain age.


These three are the ones I saw posted on the person's door (you'll have to click on 'em, to make them large enough to read):





This next one, my dad would "get"...



These next two, I found by accident while clicking on the various thumbnails looking for the three above. I'm sure there's more.

(Slag -- "Doncha think"? Yeah, I know -- wrong song.)


Again: this next one, my dad would "get"...


And I didn't include the two or three that I didn't get; clearly, some song that I'm not up on.
