I have a bunch of audiobooks and radio shows I have downloaded from Audible.com. Over time I retagged the IDs of these files to help organize them. I changed nearly everything - song name, artist, album and genre. Here's the problem I've run into... I plugged my external hard drive into a new computer, put all the audio files into iTunes which asked me for the Audible user info. I put the info in, everything copied to iTunes but ALL of my retagged Audible files reverted to Audible.com's file naming/category conventions. Does anyone know how to ID tag an Audible file so it will permanently retain custom tags instead of reverting to Audible's tags?
