Here are some WinAmp Skins for you to use. In case you don't have WinAmp installed to your PC, you can download a free version at winamp.com.

To customize the player with one of the skins, just save the image to your pc by (right-)clicking on downloads and saving the wsz-files to your wimamp-folder (e. g. C:\programs\Winamp\Skin).

Then run WinAmp and click Skins which will open a list of all skins available on your pc. Select the skin you like and you're done!
