This is nice....

file1.wav isn't really a valid RIFF file. It's close and I can hack around it, but its data chunk (where it stores the actual mp3 data) has its length specified incorrectly. The ID3v1 tag lies just outside the chunk proper. file2.wav doesn't have a ID3v1 tag, so I can't tell if this is common or bad just in this case. Anyway, I've hacked around it. Give me a few and it'll be done.
