In February 1997, U2 released "Pop"s techno-heavy lead single, "Discothèque", one of six singles from the album. The record initially received favourable reviews from critics and reached number one in 35 countries, including the United Kingdom and the United States. However, the album's lifetime sales are among the lowest in U2's catalogue, and it received only a single platinum certification by the Recording Industry Association of America. Retrospectively, the album is viewed by some of the music press and public as a disappointment. The finished product was not to U2's liking, and they subsequently re-recorded and remixed many of the songs for single and compilation album releases. The time required to complete "Pop" cut into the band's rehearsal time for the tour, which affected the quality of initial shows.
