Bearing the numerical title "4," Beyoncé 's Knowles most recent album-length collection is truly an eclectic, varied affair. Attached track genre styles range from Hip-Hop/Dancehall to Pop -tinged R&B crooners. What can be assumed to be the album's next featured single ( "Love On Top" ) is a specific piece of note; Instantaneously reminiscent of classic R&B artists like Stevie Wonder , Whitney Houston, and Michael Jackson , "Love On Top" is a simple, up-tempo ditty... accented by [ Retro-Soul ] finger snaps, horns, and backing harmonies. Credit for the song's early success is due in part to Terius "The-Dream" Nash (songwriter), Shea Taylor (producer-songwriter, alto sax), and Etta James - without a doubt, a pivotal source of initial inspiration for Mrs. Carter .
