The 'regularly updated list of Recommended Players List' (that sentence has an unnecessary 'list' in it
here) has information on it which is no longer relevant, or indeed correct, about XMMS.
XMMS has ceased development. There exists XMMS2, which is not a Winamp lookalike, but which has a client/server architecture and lots of different front-ends. The Linux media player most like the old XMMS is Audacious, which was forked from the BMP project before that turned into BMPx. Audacious still has libmodplug etc. support, though. So too does Amarok, Nautilus (the GNOME filebrowser, through Totem, I think), Banshee, Exaile, and Rhythmbox. As far as I know, they all make use of the same plugin for mod playback -- libmodplug.
I thought I should bring this up, because anyone looking to play mods under Linux would get confused by this (particularly given the fact that XMMS2 is most often not a standard package, and requires clients to be separately installed -- not particularly apparent for novices).
