A lot of problems exist that you never heard of. That doesn't mean I'm making things up. I researched the problem over a year ago, when my friend asked my help in solving it.

Just now, it took me about 25 seconds on Apple's support forum to find a post from April 12 referring to the same phenomenon: "i found with my ipod is that on some songs the music skips once or twice (momentarily stops playing and continues on like nothing happened). can't find any info on what thats because of, if you had any ideas let me know."

That's what made his iPod unsuitable for drum tracks, too.
