What is one of (if not the) best EarthBound winamp 2 skins out there. As seen at winamp.com, 1001winampskins.com, and starmen.net. I believe you just need to right-click the download link to install it.

More Winamp skins of mine can be found in Starmen.net's Winamp Skins section, under my name.
And, as always. MIDIs can be found at Ulan Shad's MIDI Page.
