Unique identifier of mp3 regardless of id3 tag?

Ideally I want a way to uniquely identify files (audio files) where things like the ID3 tag or the file name can change and the hash remains the same.

Is there a better way I don't know of to uniquely identify files? Or would I have to change my record of the file every time an edit was made? Can I hash on other pieces of data or something?

If you only count files wich have EXACTLY the same audio information as "the same" (same bit depth, bitrate, compression, etc.) its pretty easy: you would just hash the "audio" part of the file. im not too familiar with the MPEG audio codec myself though.
