As a better alternative to a giant hexdump, I've attached the first 32KB of a supposedly "corrupt" MP3 file to this post.
foobar2000 won't open the file, citing "Unsupported format or corrupted file", but Windows 7, iTunes and VLC all read the tags fine.
See the corresponding support thread (http://www.hydrogenaudio.org/forums/index.php?showtopic=90664).
