Spears traveled to Sweden to work with producers Max Martin, Denniz Pop, and Rami Yacoub, among others. Martin presented a track titled "Hit Me Baby (One More Time)" to Spears and her management, which had been rejected by the girl group TLC. Spears later claimed that she felt excited when she heard it and knew it was going to be a hit record. Her debut album was completed in June 1998, and the song was released as "...Baby One More Time" as Spears' debut single in October. The single became a global success, reaching number one in every country it charted in, became the best-selling song of 1999 in the UK, and has since become one of the best-selling singles of all-time, selling over 10 million copies.
