Songbird - sort by file name

Greetings, I routinely listed to podcasts and download a month's worth of shows each batch. I listen in the car on the way to and from work and while exercising. I would like to sort the playlist by filename, since the source names the files with a logical date string.

Songbird will not display the filename. Does anyone have a solution or can you recommend another audio player portable app that will serve this need?

Thanks!
