I came across this site today called iTunes Registry. For anyone who uses iTunes, this is an awesome tool. It keeps track of all of your music (after you upload your library in XML format), gives you all kinds of statistics about your listening habits, odd facts (like your least recently played song), and it compares your listening habits to everyone else who uses the site, giving stats on most played albums, songs, etc. All kinds of graphs and whatnot.
You can also link others to your info page. Here’s mine. Check it out.
Read a book. Preferably the book I’m currently reading. It’s good.
