I never knew till just now that you can copy the contents of your iTunes library view (or any other view) to Excel using copy and paste, on a Mac at least. This enables you to do all sorts of statto-ish calculations. For example, it turns out that since I bought this laptop (about 18 months ago), I’ve listened to 26,644 tracks, with a total playing time of just over sixty-five days. And subtotals? Don’t even get me started on subtotals.
