Have no fear, a pair of grad students have gotten fed up and have developed a delightfully simple tool for keeping track of both your MP3 library AND your favorite band’s tour dates so you won’t miss the next killer do. The tool is iConcertCal and it’s a free iTunes plugin that monitors your music library and based upon your most playlist, generates a personalized calender of upcoming shows in your city.
