Songfacts®:

• This song is a rap reworking of "Soul Bossa Nova," a 1962 Quincy Jones instrumental that was revived as the theme song for the Austin Powers movies. Jones is a mentor to Ludacris, who appeared on Quincy's 2010 album Q: Soul Bossa Nostra.
• Luda raps about coming for that #1 spot on this song. His prophesy came true: The Red Light District album hit the top spot in America, where it went on to sell over 2 million copies. He was regular at the top of the chart as this time: His 2003 album Chicken N Beer and 2006 album Release Therapy also went to #1.
• The "Hi, Mr. O'Reilly" line in the song is in response to talk show host Bill O'Reilly, who complained on his show that Ludacris was a bad role model after Pepsi hired Ludacris as a spokesman. In 2004, O'Reilly was involved in a scandal that involved inappropriate phone conversations, to which Ludacris viewed as hypocrisy on his behalf. The line comes after he says "respected highly."
• The music video has an Austin Powers theme, with Ludacris playing some characters from the franchise, including Dr. Evil and Fat Bastard. Verne Troyer reprises his role as Mini Me, and LisaRaye McCoy plays Foxxy Cleopatra (portrayed in Austin Powers in Goldmember by Beyoncé). Quincy Jones and Slick Rick also make appearances.
  
  The video was directed by the team of Fat Cats (Eric Williams and Randy Marshall) along with Ludacris' manager, Chaka Zulu.
• Ludacris performed "Number One Spot" when he was the musical guest on Saturday Night Live, January 22, 2005.
