There is a similar problem when playing (or queueing) an album through Media Monkey using OCD. However, instead of the tracks playing in alphabetic order, they play in random order. And that order differs everytime I play any album. As ronaldg says, tracks play just fine and if I play a track rather than an album the track that plays is the one I select. Fortunately, it is rather easy to sort the tracks into the right order in Media Monkey, but it means that queueing rather than playing is the better approach, because I can then sort the tracks properly before starting to play them. That makes it a three step process rather than one step, but it is one I can live with.
