Some of the best songs are motivated by being really pissed off, but the songs aren't overtly pissed, e.g. "ALL QUIET ALONG THE POTOMAC TO-NIGHT," which was spurred by a newspaper story that said (paraphrasing) "All quiet along the Potomac tonight, no officers shot -- only the occasional sentry ... " or "AIN'T I A WOMAN," based on Sojourner Truth's speech, or how about "WHAT HAVE THEY DONE TO THE RAIN" or ...
Come to think of it, a LOT of songs are motivated by pissed-offness, yes? And it's interesting to me that most of the overtly pissed off ones involve men. Women tend to get very sad rather than angry. Too bad. I've always maintained that homicide is SO much healthier than suicide.
