This is an old thread, but if anybody is still stumped by this...

... my MP3 files are named "## - artist - song title.mp3" and the ID3 tags are populated with all relevant info, including track index. I get varying results on how iDrive chooses to order the files - but that's irrelevant, to be honest, because:

Once you're playing a track from an album and you want to listen to that album in the correct order, press the voice button and say "Accept Album". iDrive will then select that album and play its tracks in the correct order.

Whether it's using my filenames to determine the "correct" order or the ID3 tag is something I can't say. But again, depending on how I navigate to the tracks (music search, browse directory, etc.) I get a different result for how the tracks are ordered. The only definitive way I've found to order the tracks correctly is to say "Accept Album" once I'm playing a track from the desired album.

Hope this helps.
