Pop-Up videos? / Japanese CDs

It's a half-hour of videos with little facts about the video, the musician(s)
and other related things that "pop up" in bubbles. It's really interesting to
see that some actor in a video who you didn't recognize before is pretty
famous now, or something like that.

Regarding the Japanese CDs having more tracks, I recall reading somewhere (I
have no idea where) that the reason "Holy Joe" is on the Japanese "Pop" is
because they finished that song late and still had time to get it onto the
Japanese copies of "Pop."

Hope that helps a little,
