More from Billboard: Edge’s track-by-track commentary on THE BEST OF 1990-2000. It’s good readin’. On “Numb”: If Bono is the great communicator in the band, and the guy who can be upfront and put across a song and a melody and a lyric, my approach is much more quiet, internal… There’s humor there, there’s a lot in the lyric, but it’s not put over like a lead singer would put over a tune. It’s really deadpan; it’s really understated. So, if ever there was a song that was kind of designed for me to take the vocal, it was this tune. In a way, it was kind of the anti-communication, anti-frontman, anti-lead singer song. I can’t imagine ever doing anything like it again.
