you can still get the old winamp (2.3), from before it got all maimed by AOL, if you look hard enough. I use it mostly for nostalgic reasons: old skins and AVS scripts.
As you said, Winamp + classic skin, with all the "features" turned off like Winamp Agent and those other stupid things they added after the AOL acquisition, is perfectly fine. The fact that OP didn't even try out (or discover) foobar2000 tells a lot.
I think most people are being sensible when they opt not to run unpatched software from 15 years ago.
