Red Hot Chili Peppers seem to often mention various states in their songs. I wondered which states made the cut through the entire Chili Peppers catalog, so I downloaded all of their lyrics and parsed them for state names. Here is the result:

AL, AZ, CA, IN, KY, LA, MI, MN, MS, ND, NJ, OH, PA, TN, WI

Looks like it could be some weird political trend.

I should note that one song mentions Kansas City, and I didn't count that as Kansas (or Missouri). Also, one song has the below lyrics in it. Given that it doesn't make reference specifically to NC or SC and that Carolina is most likely the name of a person, I left it out as well.

All in favor sign the waiver
Bloody carolina won't you
