A while back, I posted on the iTunesRegistry website. It’s a fascinating way to analyze your music listening habits in ways that iTunes itself doesn’t track.
Anyhow, I just updated my account with current data. For any of you curious enough to want to see it, here’s the link:

If you primarily listen to music in iTunes and have an account there, feel free to post your account in the comments.
