Look to the right. Yeah. It's cool and you know it. At least you wish you had something like this on your website.
I use the last.fm/Audioscrobbler plugin for WMP, and they make all kinds of XML/REST feeds available for user stats (example). I decided to throw my top 100 artists feed on the site just for fun. Now you know what I listen to all day.
So when you see Winger get into the top 5, you know there's a bug somewhere.
