After being signed to Jive Records in 2004, Brown began recording his self-titled debut studio album in February 2005. By May, there were 50 songs already recorded, 14 of which were picked to the final track listing. The singer worked with several producers and songwriters--Scott Storch, Cool & Dre and Jazze Pha among them--commenting that they "really believed in [him]". Brown also made some input on the album, receiving co-writing credits of five tracks. "I write about the things that 16 year olds go through every day," says Brown. "Like you just got in trouble for sneaking your girl into the house, or you can't drive, so you steal a car or something." The whole album took less than eight weeks to produce.  Released on November 29, 2005, the self-titled Chris Brown album debuted at number two on the Billboard 200 with first week sales of 154,000 copies. Chris Brown was a relative commercial success with the time; selling over two million copies in the United States--where it was certified two times platinum by the RIAA--and three million copies worldwide. The album's lead single, "Run It!", made Brown the first male act (since Montell Jordan in 1995) to have his debut single to reach the summit of the Billboard Hot 100--later remaining for four additionally weeks. Three of the other singles--"Yo (Excuse Me Miss)", "Gimme That" and "Say Goodbye"--peaked within the top twenty at the same chart.  On June 13, 2006, Brown released a DVD entitled Chris Brown's Journey, which shows footage of him traveling in England and Japan, getting ready for his first visit to the Grammy Awards, behind the scenes of his music videos and bloopers. On August 17, 2006, to further promote the album, Brown began his major co-headlining tour, The Up Close and Personal Tour. Due to the tour, production for his next album was pushed back two months. St. Jude Children's Research Hospital received $10,000 in ticket proceeds from Brown's 2006 "Up Close & Personal" tour. Brown has made appearances on UPN's One on One and The N's Brandon T. Jackson Show on its pilot episode.
