I have my entire library in mp3 format and all CD's have been imported by iTunes. I forgot my iPod today and connected in to download some tracks at work. To my surprise the iTunes at work didn't see any of the artist/album/track info. I blew it off as a strange download issue. When I got home tonight I decided to grab some of the files from my backup external and load them into my son's iTunes on his macbook and it has the same issue. Does the track information not get stored in the individual files? I see all of the info in my master iTunes library. I'm now concerned that my backups may be impossible to import in the case of a disaster. I've ripped hundreds of CD's and the thought of doing that again makes me sick.
