handled by Beyoncé and Taylor. From June 16 to June 27, 2011, the songs from 4 were available to listen to in full each day on Beyoncé's official website, paired with its accompanying photo spread from the album packaging and a quote. On June 26, 2011, "Love On Top" was the eighth song to be chosen. The quote found Beyoncé elaborating on the song's inspiration: "When I played Etta James [in the 2008 musical biopic, Cadillac Records] it was the most I'd learned about myself until the recording of this album. When I went into the studio I used the same passion, honesty, and approach with my vocals I channeled as Etta James. It does not sound like the vocals on my past albums. It's a lot rawer. It comes from a deep place." Beyoncé, who has covered "At Last" which is a song originally recorded by James, portrayed the artist in the 2008 musical biopic, Cadillac Records and won critical acclaim for her portrayal. She told Billboard magazine: "I realized that Etta James was so unapologetic, bold and strong that playing her was a big risk for me. It gave me the confidence and the push to challenge myself a little more with my music." "Love On Top" impacted Urban radio in the United States on January 10, 2012, as the fourth single from the album in that country. Composition "Love On Top" is an up-tempo R&B and disco song viewed as a modern take on old school music. It also exhibits elements of retro-soul music, retro-pop, 1980s pop music, funk music, jazz, and 1970s classic disco music, as stated by Joanne Dorken of MTV UK, Cameron Adams of the Herald Sun and Thomas Conner of Chicago Sun-Times. According to Slant Magazine Eric Henderson, "Love On Top" is a "bright, breezy tribute to the freshness of mid-[19]80s, pre-new-jack-FM R&B reminiscent of Whitney Houston and Anita Baker." He also said the song was the "perfect and totally inverted fraternal twin" of another song on 4, being "Rather Die Young". "Love On Top"s retro elements are further illustrated by its use of finger snaps, a "distorted" bass groove, and a melding of horns as well as sweet backing harmonies, especially in the bridge and the chorus of the song. It is instrumentally complete with a thumping bassline, synthesizers, tribal drums, an electric piano, a guitar, a peppy saxophone, and some backing
