Isn’t there are non perl way to do this?

Martin says:

Well you can basically use any mp3 tagger that you like and remove them manually.

darkkosmos: of course :) I just wanted the fastest way possible of looking for anywhere they might have put personal info, and I write perl all day, so using MP3::Tag was it. I could write the same thing in C, C++, python, lisp, or any other programming language. It’s basically just reading a file and parsing it into it’s parts. I threw those together in about 5 minutes total.

Does anyone know if the Amazon MP3’s have personal info and, if so, how would you remove it?

keck says:

Good idea! I happen to have some, so I ran http://perlhack.com/mp3_utilities/list_tags.pl.txt on them. Here’s a snippit:

############# COMM #############
$VAR1 = {
‘Language’ => ‘eng’,
‘Description’ => ”,
‘Text’ => ‘Amazon.com Song ID: nnnnnnnn’,
‘encoding’ => 0
};
$VAR2 = ‘Comments’;

Where the ‘nnnnnn’ is the Song ID from Amazon. There is also an APIC (attached picture) as in rhapsody’s mp3’s, but it is probably just the cover art.

Either of these outfits (or anybody else) could also be adding identifying info steganographically, so it’s still on you if you share them :)
