Music track order from DLNA media server

The files are named after the song title. I’m not even sure where Track 1etc is coming from, none of the MP3 metadata contains “Track X”, is this derived from the track # metadata? If so, surely this field is treated as a numeric and should be sorted as such? I don’t understand how this DLNA server is treating the files - anyone care to shed some light on it…all I want to do is listen to an album in the correct order!!!
