I haven't used Winamp since I went Mac (like 2006). It's the only thing I missed about Windows.
VLC is my media swiss army knife, but I'm also pretty OCD with my music library. I only have full albums and I'm generally listening to one album at a time. VLC can handle more than that, but for music I just drag and drop the folder into VLC. VLC also handles most video codecs without requiring any other installs. So yeah, I use it for all media.
