I've done it! I've successfully incorporated an RSS feed of my iTunes history into my blog - now you can see what I've been listening to recently (included above the current track is a link to my AudioScrobbler profile, so you can get a more indepth look at my listening habits). Also, thanks to Jason's link, I've been able to put together several editions of the new 'South Park' version of me - which will serve to let you know how I'm feeling on a given day. All of this is now available in the sidebar for your perusing pleasure.
It's really a minor thing, though - real time music? Who cares? - so I'm content with things the way they are. When I get my own server and domain, then I'll be able to host the code myself, and I can do my own realtime automatic updates, rather than mooch off of benevolent bestowers of bandwidth.
So now I've got my music, my mood, and my mind all on display. Yeah - exhibitionism, here I come.
