Audiobooks ID3 tag? ID3 tag editors?

Thanks for the tips here.  I just got an mp3 audiobook that had the tracks all screwed up (10 “CDs” with tracks numbered 1 - 8). 

The MP3Tag utility’s “auto-number” feature was brilliant.  Saved me a lot of grumbling.

I did notice a latency with the MP3Tag directory browser - the Clip didn’t show up right away in the browser.  It did after a little while (of course by the time I noticed the Clip *was* showing up in the MP3Tag directory browser, I’d already copied the mp3 files to a local drive, renumbered the tracks and was in process of copying them back to the Clip via Windows Explorer).  But anyway, it worked, and I was happy!  Thanks!
