Input: Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan. The album's official lead single, "Never Ever", which features Young Jeezy, was released in the United States in January 2009 and reached a peak of number nine on the U.S. Hot R&B/Hip-Hop Songs. The second single, "Love Sex Magic", featuring Justin Timberlake, became a worldwide hit, peaking within the top ten in twenty countries including the U.S., where it peaked at number ten on the Billboard Hot 100. It went on to be certified platinum in Australia and received a gold accreditation in New Zealand. It received a nomination for "Best Pop Collaboration with Vocals" at the 52nd Annual Grammy Awards and also for Best Choreography in a Video at the 2009 MTV Video Music Awards. "Like A Surgeon" was the fourth single from the album. The song received no promotion and no single cover nor music video was released. However, the song did manage to peak at number fifty-nine on the Hot R&B/Hip-Hop Songs chart from airplay alone. "Work", the final single, achieved moderate success in international markets.
