With the searching options and playlists in mezzmo it is a shame that it can not easily be leverage on the device that you use to play it from. Could it not be possible that based on the device you could force the sort or column to be used instead of the default that is sent to the device? Using the xbox it takes the title of the filename and sorts on this. If you could transform and server up a different column it would allow sorting and even more flexible sorting to the end user based on the device.
