Looking for a MP3 IDv1/IDv2 Editor

Hi, I am looking for a MP3 Tag Editor that will edit multiple files IDv1/IDv2 information versus doing it manually one file at a time. Example, several files at the same time with a string in ALL the titles that I want to search for and replace, (like a Word processor File Find/Replace feature). Does such a program exist?
Thank you… :confused:

Windows media player will let you edit multiple file’s tags at once.
Like putting all the same artist or something.
