There is a great resource out there at the intersection of music and economics that deserves more coverage and more use. Check out From ABBA to Zeppelin, Led: using music to teach economics and prepare to be astounded at the number of lessons you can pull from popular (and not so popular) music. If you are a teacher looking for a hook to pull your students in, this very well could be it. Sure, there are obvious selections like Oingo Boingo's "Capitalism" and "The Gambler" by Kenny Rogers. But you've really got something when you can find economic wisdom in "Milkshake" by Kelis.
