mpcABX

mpcABX is a super simple ABX comparator for MPD.
It does just the absolute minimum, with a textual interface, no errors checking, etc., so another MPD client is needed to setup the playlist, set outputs, volumes, etc. The A & B tracks will simply be the firsts two tracks in the current playlist.

Being written in plain Python and using no additional libraries, it can work just about anywhere with no modifications.
It has been tested on Linux & Win PCs, as well as on Android with SL4A and on a Raspberry Pi.

Here's a quick look at the interface:
