This is the WACUPified version of the Winamp 5.666 classic base skin.

Other than a bit of Winamp to WACUP branding changes (as was also done by spotiamp/spotiamb & a few other media players from over the years) the main difference is the images are stored as PNG (as WACUP natively supports) & it fixes some visual issues present in the image files which were more noticeable when using it in double-size / 2x view mode - oh you lucky people to have 4K monitors ;)
