I've set up a new Windows 7 / Windows Vista gadget site at http://www.uniquewg.com
. All gadgets are free to download and more are being added on a regular basis. The official gadget site has become too bloated with garbage now, so I created some gadgets myself and set up the website to provide downloads.
The "Beat Music Player" gadget has been my biggest project so far and can be used to listen to music in your WMP library (without WMP running). It provides cover art support and the ability to queue songs or albums.
Let me know what you think!
