The Best Funny And Educational Geek Songs (skorks.com)

Not in the list but my vote (on the funny, rather than educational front) goes to Monzy (http://www.monzy.com/) with So Much Drama in the PhD. He even did a gig at Stanford! Audio on YouTube: http://youtu.be/JimUMZTiAjo

MC Plus Plus (http://www.mcplusplus.com/) is good in the nerdcore rap scene too.

A favorite of mine not on this list is They Might Be Giants' "Why Does the Sun Shine?"

Here are the lyrics: http://www.sing365.com/music/lyric.nsf/Why-Does-the-Sun-Shin...

An oldie but a classic - http://content.flashtrackz.com/games/files/internetkilledthe...

I would kindly suggest "The Presidents" by Jonathan Coulton: http://www.youtube.com/watch?v=DdUUywIsIGI

I must admit, I like this version of Code Monkey better: http://www.youtube.com/watch?v=qYodWEKCuGg
