My mp3s are behaving badly

[The Brain]

Maybe Lennon is trying to tell you something.

What player are you using for your MP3s? And have you tried playing the weird MP3s through a different player?

Also, just for a lark, if you're using a flavor of Windows, what happens if you highlight and play the MP3 through Windows Explorer? (If you don't know how to do that, just single-click on the file itself, and a small version of Media Player should pop up under the description area on the lefthand side of the screen).
