TrackMonkey is an app that sits in your systray, and will send the name of the currently playing track to a script on a remote webserver, which can then be used for various purposes, e.g., displaying the name of the currently playing song on your website. Official site at http://www.oddbox.org/~gabe/
Fairly easy to set up and configure... sends the info of the track currently playing in Winamp to a remote webserver. Plus it has a fresh monkey logo.
