Glitch in Metallica's "Disappear" at 03:20

A few months ago, not wanting to buy the stupid MI2 soundtrack for one song, I got Metallica’s Disappear off Napster. After burning it onto a CD I noticed a small glitch right around 3:20, right before the instrumental chorus starts. I figured it was either an error in the burn or an MP3 artifact, but every copy of it I’ve downloaded has it. Is it on the CD itself?

I don’t have the CD, but it is that way on the radio, MTV video, and on the MI2 DVD, so I suspect it is intentional. Besides, I like it.
