IMO at this point WinAmp does not offer anything beyond name recognition and nostalgia. Isn’t qmmp essentially an open source version of WinAmp?
Even as nostalgia, I just tried out loading a winamp skin from the winamp skin museum someone linked further up with qmmp and it handles that just fine too. So I’ll be just using that going forward.
Sadly political strikes have been forbidden here for a long time already.
