@Gary-K Have you tried renaming your track files, to include a leading track number? E.g.
01 - Hello Goodbye.mp3
02 - We Can Work It Out.mp3
etc.
If that's the case, it's not too difficult to write a (e.g. Linux bash) script, to extract track number from the metadata, and rename the file appropriately. You'd need something like mp3info, or metaflac to get the track number metadata.
