The iPod handles the ID3 tags through its playlist which is simply a listing of a songs title, album, artists ect. The ID3 database template stored on the iPod was already created with all the fields pertaining to the song by the manufacturer of the iPod, the Title, Album, Artists, ect in accordance to the ID3v1 and ID3v1.1 formats. The ID3 tags are embedded inside the first 128 bytes of an mp3 file inside its header (actually its 125 bytes minus 3 reserved for the first 3 characters for the string "TAG". There are two versions of ID3 format, ID3v1 and ID3v1.1. The only difference between ID3v1 and ID3v1.1 is that the additional field Genre had been added to the TAG and that the comment field has been shortened from 30 to 28 characters. The iPod simply stores the file extracts and displays the ID3 tags from the mp3 files when a mp3 file is copied to a playlist on the iPod. Based on what information the ID3 tag contains inside the mp3 file such as title and artist it will display those items in the playlist. If the full information is placed into the ID3 tag it will display the album, title, artist even genre if its listed.
Some songs may just have title and artists while others may contain the full tag. BTW this is partially how the RIAA distinguishes the difference between legal and pirated mp3 files. The legal mp3 files have the ISRC or International Standard Recording Code number which is a 12 character alphanumeric string embedded inside near the end of the ID3 tag which contains the fields: ISO Country, e.g. GB for the UK, or US for the USA, DE for Germany, etc Registrant Code, a three alpha-numeric unique reference Year of Reference, the last two digits of the current year, e.g. '03' for 2003 Designation Code, a five digit unique number, e.g. '00013' The ISRC is a signature which serves as a method for tracking and distribution purposes if not only for copyright protection. Its sometimes best to keep to the naming standard Artists-Album-Track-Title.mpg but you can just use title.mp3 just as long as the ID3 tag is embedded inside the mp3 file with the other information. iPod will take care of the rest. It simply stores the file and sorts them based on the ID3 tags.

This is sounding better. I've been ripping my CD collection to mp3. I've currently ripped about 175 CDs. Based on what you've stated, it seems I'll be able to simply copy the mp3's to the ipod or in reverse direction. With my current ripping parameters, I'm projecting a 580 CD capacity on the 60 Gb ipod. (256, variable bit rate, high quality, 5-6:1 total compression). I'll be able to squeeze the current collection onto the ipod with a little room left over (I haven't counted the CDs yet, but I have somewhere between 400-500 now). How does the ipod manage the ID3 Tags? Do I need to rename the mp3 files to meet a certain naming convention for the ipod (e.g., Artist-Album-Track-Title.mp3, etc.,)? Or, does the ipod simply store the file and sort on ID3 based on how you search? Thanks for the help. I know that the day these are delivered, my wife is going to want hers with music installed and no problems.
