I just came across this video on youtube the other day and then I discovered that there’s a whole site dedicated to science tunes. The site is called Kevin Ahern’s Wildly Popular Metabolic Melodies and it has songs in both MP3 format and a few youtube videos. Kevin wrote the songs for classes that he teaches at Oregon State University. The list includes 49 songs and has been updated as recently as May 9, 2010. The songs don’t reach the professional level of the PCR song or GTCA but they’re still worth a listen.
