Okay, so I did a Napster search for "99 Luft Balloons" (because I'm in an 80's kind of mood), and mixed in with Nena's version there were several listings for a cover by Bjork. Cool! thought I, and I proceeded to download. I also downloaded the original. Upon listening to both, I can not tell one single difference. So, is it that Bjork purposefully made her cover sound just exactly like the original version, or is it that some dumb young person (or persons, as there were several listings for this particular MP3), having never heard of Nena, listened to the original, said to themselves "I'm not absolutely positive who this is, but it sure sounds like Bjork!" and labeled it as such? I'm guessing it's the latter. I've a feeling if Bjork had recorded the song it would have an unmistakeably Bjork sound.

My Swedish Chef impression: "Bjork! Bjork! Bjork!"
