Songs-DB can use WinAmp2 skins for its media player. If you want to change the default skin to some which more fits your style, just download it, put it to Songs-DB's skins sub-directory (usually C:\Program Files\Songs-DB\Skins) and select Setup Appearance from the main menu. Then you can browse all your skins and confirm the selection when you are done.
The best source for WinAmp skins is the huge collection here.
If you have any skin you really like, just let us know and we will list it here in order to allow others to download it!
