> "It really whips the llama's ass!"
(I feel like I should apologise for such a low-effort comment, but .. That phrase is the first thing that comes to mind when I remember WinAmp, and if you're going to make a one-line "praise" comment about Winamp it's the only one you should need!)
What I remember about Win Amp in the (90's?) was how customizable it was and how many features it had. It was really flashy and advanced for that time period.
It's been years since I've used it, I don't use Windows much anymore.
