Well, not really -- they've been autotuned by a talented Youtuber called Melodysheep, who's made a number of great, toe-tapping videos that make you think, like this one, in which a number of prominent thinkers and scientists discuss the nature of science itself -- ultimately characterizing it as "the poetry of reality." I like that.
Alan Watts was a philosopher and a Buddhist and was nearly as quotable as Carl Sagan (who I blogged about yesterday) -- and in this song/video he discusses the nature of the self, and the fallacy of conventional ideas about personality and selfhood. The universe is a system, and we are no more separate from that system than any other part of it.
In this next video, Melodysheep assembles the case for a manned mission to Mars, and puts it to music. It's pretty convincing -- though I'm not sure how much of that is just the catchy tune.
This next video features David Attenborough, Jane Goodall, and Carl Sagan, and it attempts "to explore the wild diversity of life on our planet, the intricacy and origin of its mechanisms, and its close relation to all other life forms" (according to Melodysheep).
One of my favorites is this music video of the 1969 moon landing.
