Beautiful Pain

Sia Furler sings the hook on this track. The Australian singer-songwriter has sung on hits for David Guetta ("Titanium") and Flo Rida ("Wild Ones").

Sia, who is openly bisexual, was criticized for working with Eminem after The Marshall Mathers LP 2 album featured seemingly homophobic lyrics. The Australian songstress asserted that she doesn't think Eminem is anti-gay, telling The Huffington Post that, "she was under the impression that Eminem's alter-ego Slim Shady was performance art, and a thing of the past," adding that she does not believe the rapper is actually homophobic. Sia eventually donated her share of profits from the song to the L.A. Gay & Lesbian Center.
