» Winamp is a media player for Windows that was very popular in the late 90s and early 00s. It features a highly customizable UI through the use of "skins" - and back in its heyday, I made a lot of them!
Here they all are!  Every now and then, I make a new one!  Rirath and katoh contributed a couple of 'em too.  Want more?  Check out the Winamp Skin Museum for more Classic skins!
