Excerpts

Module files can be very compact. A full song can fit into less than 1Kb. For example, the song Minimal III by SofT MANiAC in XM format is just 905 bytes without compression.
Page 5, added by AngelArt957.

According to the author, Minimal III (or «mini.xm») is the smallest original composition in XM format. It was created by SofT MANiAC, aslo known as ReSampled, a Russian music producer, for the uFMOD library.
