After 15 years, Winamp is shutting down. I actually wrote the obituary for Winamp back in 2004 when it was widely beleived AOL was abandoning the player, but it seems I was 9-years early.
Winamp was my preferred player for MP3 files for years because it was so light on its feet. Before the bloat set in, there was nothing faster. I miss the old Winamp.
If you're running Windows, you can still download the old bloat-free versions of Winamp here.
