FST Music Chart (updates on Sunday, until then it's a bit bare).
I posted this a while back in the music thread but I thought I'd post it here (in the lounge) to see if anyone else was interested.
Basically it builds a profile of your music tastes. Here's mine. It's fairly useless really but oddly compelling.Audioscrobbler builds a profile of your musical taste using a plugin for your media player (Winamp, iTunes, XMMS etc..). Plugins send the name of every song you play to the Audioscrobbler server, which updates your musical profile with the new song. Every person with a plugin has their own page on this site which shows their listening statistics. The system automatically matches you to people with a similar music taste, and generates personalised recommendations.
You just need the relevant plug-in from here: http://www.audioscrobbler.com/download.php#Winamp
The register an account, input your username into the plug-in on your player and you're all set.
You can join some fellow FST'ers here so that each week a joint chart is compiled. Everyone is welcome to join our group.
Note: If you have problems getting it installed I can try and help if you PM me.
Edit: Oh, yes. And you can do those gay-ass "What am I playing now" sigs that people seem to like.
