Ok here is my question, I hope i am in the right spot. I am looking for a way to add Metadata to my MP3 and MP4 (video's) so that it can be seen in itunes or my PS3. I currently have things sorted out into folders, this keeps everything pretty well orginized. I want to make sure that if a file is transfered to another computer the data comes with the file. Does that make sense? with my MP3's the data like artist/track/album/genre is part of the file I want this for my MP4 (video's) too. I know itunes lets you add this info but I am not sure it is written directly to the file or some itunes Database. please keep in mind i am using a vista PC. if I had a Mac i would use lostify which looks like a great program. I have found nothing of this calibur for windows.
