for her and making it her own." For "Babydoll", Carey teamed up with Elliott. The track was recorded in Atlanta, where Elliott resided, and included background vocals from Carey's long-time friend, Trey Lorenz. "Babydoll" is an R&B ballad with trip hop and drum and bass influences, and was described as "a vocally driven piece", with strong jazz harmony provided by Cory Rooney. Other songs that incorporated R&B influence into ballads were "Whenever You Call" and "Close My Eyes", which were personally important to Carey due to their lyrical content. While both were similar ballads to Carey's previous work, Nickson said: While up to the standard of anything Mariah had ever done before, [they] suffered in comparison. But even here you could hear the new Mariah in the spareness of the arrangements and the way it was her voice, rather than any instrument, that controlled the song. She'd grown to the point where having less behind her really proved to be more, for the song and for her. It was notable, too, that like the other ballads on the record, these two leaned very much towards R&B. Carey wrote the song "Fly Away (Butterfly Reprise)" with famed house music producer David Morales. When imagining the concept for "Butterfly", Carey intended the song to be a house music record, but after writing it, made it into a ballad. Carey expressed a desire to feature her concept both on the house record, in addition to the ballad that would become "Butterfly". Morales took Carey's lyrics, concept and melody and added a house beat to it. For the album, Carey recorded a version of Prince's "The Beautiful Ones", featuring Dru Hill, with Dru Hill lead singer Sisqó sharing much of the lead with her. The song was one of the last recorded tracks and was the only non-original song on Butterfly. The final song on the album was "Outside", a ballad that was written by Carey, Afanasieff and Rooney, about Carey's experience being biracial. Richard Harrington from The Washington Post described the album's subtle inclusion of both pop and R&B genres: There are two Mariah Careys on Butterfly. One is the pop-oriented, ballad-leaning traditionalist who works very effectively with her longtime professional partner, composer-producer Walter Afanasieff. The other is a self-styled hip-hop fanatic who worked with Ol' Dirty Bastard on her last album and teams up here with several of that genre's movers and
