Winamp does a fairly good job too: that's what I use. I installed a few plugins so that .mod, .xm, .tmfx and .sid files are played 'natively'; exotic .dw-files I converted to MP3s first with Deliplayer, which then was no longer required. Octamed never caught on in games and demos because it was released very late as well as being a major CPU hog in playback, so little popular music in that format exists.
