xmms2: Could not connect to xmms2d: xmms2d is not running.

I came around this error, it means that the daemon and the client don't run in the same directory.

xmms2d -i unix:///tmp/apantutarinte export XMMS_PATH=unix:///tmp/apantutarinte xmms2 list

helps alot.

Edit: this is no more necessary with DrGonzo release.
