I'm giving AudioScrobbler a try. It's an online service that hooks into your MP3 player of choice (including iTunes!) and takes statistics on what you're listening to. The top 1000 songs played chart (with a surprisingly dull #1) and top 1000 artists chart are both an interesting look into the musical psyche of the digerati. These sorts of toys don't usually entice me, but I'm giving it a go, and I know some people are using AudioScrobbler and RSS Digest to show "recently played" lists on their blogs.

My Audioscrobbler page doesn't contain very much yet, as I only just installed it, but if I keep it up, it might prove interesting in a week or two.
