In "Discotheque," who is the not-Bono voice that dominately sings throughout several parts of the song (most noticably, "You know you're chewing bubble gum...")?
Also, I'd be interesting in knowing what you people think of "Pop" as an album. I think it's pretty good; I liked the style of "Hold Me Thrill Me Kiss Me Kill Me," and a lot of the stuff on Pop has a similar feel. That said, I think that half of the songs on the album aren't up to par with U2's regular standards. I loathe "Miami" with a passion, in particular.
My favorite songs are "Staring at the Sun" and "Wake Up Dead Man."
