Is this how things start these days?

I saw this in the Guardian Guide booklet, forgot about it, Googled it, found an article on Gawker and clicked through a link from there to get to this flickr set.

The idea orginally appeared in Village Voice as part of a witty satire on rap music. People have come up with their own take on it and flickr has been the seedbed for the result.

Songs expressed as graphs and functional diagrams. Funny and strangely satisfying to decode. It's like sharing an in-joke which is how I think music and poetry work, although across a broader span of emotions than humour. I do, I really think that.
