Pop has been unfairly dismissed as a disappointing U2 album. Part of this is the band's own fault. They made it very clear they were forced the rush the completion of the thing to accommodate tour deadlines, and they've remixed many of the songs on later compilations. The material is rarely played in concert and members of the band (especially Larry Mullen, Jr.) have slagged it off over the years.
It's not their best album, but songs like "Please," "Gone" and "If You Wear That Velvet Dress" are pretty brilliant. The album starts with dance songs like "Discoteque" and "Do You Feel Loved," and slowly gets darker and darker until it ends with a funeral on "Wake Up Dead Man." The critics tore it apart and the PopMart tour struggled to fill stadiums in America. It seemed like the band was finally on a downward trajectory, but U2 always does their best work when their back is against a wall.
