Very cool! the whole thing could use some zooming in, everything looks very small it todays high DPI displays. Its OK to be a bit pixealted, We've looked at these on 800x600 CRT monitors :)
This did not happen on mobile devices although they are all also 4k now. I think the main reason being that our fingers aren't any smaller either.
Found titipoco again. I know I have a backup of it on a CD-R but no longer have an optical drive to read them..
On topic, where everyone mentions "their" winamp skin: for me, winamp is the pale blue of the inconsistently named trainatron/trinatron. Always on top, always minimized to shade, only expanded to toggle the playlist shade (but usually operated simply by drag&dropping album folders).
One time ordering was broken when windows stopped to supply files in alphabetic order so I had to make a plugin that took care of that (my files are certainly named with padded index prefix). That plugin might have been the most wonky piece of c++ routinely ruining on my system, but it did the job for quite some years.
I'd wager that if your screen pixels are "too small for comfort" you or your graphics setup hasn't gotten scaling right yet.
That said, it doesn't seem to center the scaled version in the window in Firefox so it's not very usable.
