Error streaming some (not all) music from mpd

[aronson]

I have found that some songs in my library (possibly only ones I get as a part of all-access) create this traceback in my logs and play only a split second of each track affected:

I suspect that playing some tracks stops after a short time is indeed related to the missing All Access support of the current release. It should have been fixed by #9.

The error you reported in the log file seems to be caused by an optional (missing) year field of a track. This is indeed a bug, but should also be fixed in the current development branch.

Is it possible, that you try the current development snapshot? Please note, that you will have to set the mobile device ID of your registered Android device in the Mopidy config file, as described in the README.rst of the plugin.

Fixed in v0.2.
