Ach, Winamp is a sad story. They were so /good/ in the 2.x days, before the bloat and before AOL couldn't decide what do to with it. I still have a few Winamp skins ("TubeAmp" was my favorite) that Audacious can use, but on Windows I have switched entirely to Foobar2000.
I was one of those people who switched back to 2.xx from 5.x, running 2.95 for a *long* time before I got tired of something-or-other not working right and going to Foobar. I still have some of the Winamp hotkey commands imprinted in my brain; it's mildly annoying that FB doesn't have a mod to switch its hotkeys over to Winamp's.
Interesting parallel to ICQ: they're another (former) AOL acquisition that's basically died in the USA but popular in foreign parts.
