On January 10, 2004, American Idol host Ryan Seacrest took over the hosting duties of "American Top 40" from Kasem, although Kasem would continue to host "American Top 20" and "American Top 10" until his retirement in July 2009. With the host change, "AT40" underwent a makeover, using a new theme song and introducing several new features. These extras included interviews with celebrities (which were not restricted to musical or countdown artists), a gossip section, and an update on movies screening in cinemas. Other extras inducted on a regular basis include "AT40 Breakout", a song predicted to crack the chart within the next few weeks (formerly known as the "Out of The Box" hit); "Request Line", a segment in which Ryan Seacrest will play a song requested by a listener; "Double Play", a former hit from the artist just played; "AT40 Sleaze" (inspired by the "Dees Sleaze" segment of the "Rick Dees Weekly Top 40" radio show); and "AT40 Rewind", a hit song from the past decade or so. In between songs, Seacrest and his guest hosts often make deadpan one-liners while writers and producers can be heard laughing frequently, including the security guard "Roger". Additionally, Seacrest initially opened most shows by playing the previous week's #1 song, as Kasem often did in the 1980s; this was discontinued after 2006, but in mid-2009 Seacrest began including a shorter recap segment in the show's introduction, in which he would play brief segments of the previous week's top three hits. In December 2004, the Hot AC version of the show debuted, giving both Seacrest and Kasem competing countdowns in the same format until 2009.
