I don't have an iPod, what I DO have is a 500MB pen drive attached to the MDI. It plays the tunes in artist alphabetical order. They're mostly MP3s and I've edited the properties of each one to artist & title, eg Emser Evodia. I can skip backwards and forwards, part way through a tune and it will always display the correct name of the tune. I didn't copy the tunes onto the pen drive in alphabetical order, but the TOC is read in alphabetical order and that's how they play.
The tunes were mostly downloaded from a recording web site that I frequent and they're all talented amateurs (especially Emser).
