This is the coolest little app I’ve come across in a long long time: iConcertCal is a free iTunes plug-in
that monitors your music library and generates a personalized calendar

How cool is that?

I have had some stability problems with iTunes since installing this; Any import of a few songs at a time and iTunes crashes; Uninstall resolved the problem . . .
