Feed the Animals

I dunno if this is new to anyone else, it's a month old, but I just found this link (and its siblings) and it blew my mind.

Rather than trying to explain from my own ignorance:

And grab it here for name-your-price, but I think the videos are alot more fun - I'd have a hard time recognizing all the music on my own.
