CHICH.MID (or its full title, “Come to My Circle, Chichiburrin”)
Rather more atmospheric than most Zan tunes, might suit an inter-message screen or some sort of ZDoom-y cutscene effigy concepteroonie. Deliberately quiet and thoughtful; deliberately does not loop. Used in Hexasketch MAP02, and before that submitted to a big battle on battleofthebits.org where it did well! Yay! Might overflow MIDI channels in a stricter Doom port.
