Hi, I also have some audio books in multiple parts in mp3. Many of em' have over 20 parts. I just wished there was anyway to organize the parts into a seperate folder using my computer. It's no fun having to spead 15-20 minutes during it on the Kindle. Is not like I'm getting paid for it, right ?
Also, I agree that player is rather awful. It's as basic as it can be without it falling apart, really. I do hope they'll update it soon.
