I'm releasing a new weekend coding project. Tunalyzer
It analyzes your iTunes library and shows aggregate play times for songs, artists, albums or years. I wrote something like it last year as a simple jscript. This is a gui application written in Python. I'm calling it version 0.5.0 because there are a few features I want to add (like Mac support), but the core functionality is there. I've only tested on Windows 7 and I don't know if the installer works for XP, but I promise Tunalyzer won't destroy your computer or your iTunes library.**
