Hash-check for MP3 files
Is there a hash-check algorithm for MP3 files which generates a hash-code based only on the MP3 audio data and not the tags?

I ask, because many I re-tag almost every MP3 file I have at one stage or another. In fact, I'm using the playcount plugin for foobar2000, so the MP3 file changes every time I play it, therefore standard hash-checks become pointless, unless there is one which ignores the tags on the file?

there's one inside the LAME-Tag...you can take a look at it using Mr. QuestionMan -> http://www.burrrn.net/

--alt-presets are there for a reason! These other switches DO NOT work better than it, trust me on this.

There is a utility precisely for that. It was mainly made for NES and SNES ROM dumps, but it works for MP3. It ignores the headers, and probably the tags.
It's called duper and you can get it at zophar.net under utilities.

so how do I get the program to save a checksum for mp3's? All it does is saving the size of the mp3...the checksum feature only works for roms as far as I can tell...

I don't know of any program that is able to do that, but you could try to make a batch file, that 1) makes a copy of your mp3 file, 2) strips off the tags with tag.exe, 3) uses a <hash calculator of your choice> to create a checksum and print it to the screen or into a file, 4) delete the copy, 5) move on to the next file
