Hmm... I'll look into it and get back to you.
EDIT:
Wow, I don't see why, though I'm just peeking at the file attributes through finder. Are you running Vista? And, though I'm not very familiar with MP3, isn't it supposed to 3-layer instead of 2?
(also, nice, ~200kbps bitrate -- much higher than most mp3s are set to)
