This Ubuntu package contains a plugin which lets you play Amiga AHX chiptunes using XMMS.
For those unaware: AHX was a tracker-like music making program for Amiga computers that produced sound similar to Commodore 64. It was developed by the Abyss group and is still popular among oldschool demosceners.
You can get some AHX tunes from Kamson’s lair.
