 The downtempo song was developed on the following day, with Madonna writing the lyrics and Leonard composing the melody. Named "The Look of Love", the song contains the line "No where to run, no place to hide. From the look of love, from the eyes of pride". After "The Look of Love", Madonna went on to develop two further songs with Bray as the producer. The first was called "Causing a Commotion", and was inspired by Penn and the couple's often tumultuous relationship. Madonna felt that her marriage to Penn was on the verge of breaking-up, due to Penn's abusive and violent nature. In a Rolling Stone article dated September 10, 1987, Madonna spoke about Penn's impact on her life and the song: "I don't like violence. I never condone hitting anyone, and I never thought that any violence should have taken place. But on the other hand, I understood Sean's anger and believe me, I have wanted to hit him many times. I never would you know, because I realize that it would just make things worse. [...] I felt like he was' Causing a Commotion 'to purposefully distract me. I wrote this song and vented my frustration in it." The last song developed was "Can't Stop", a track inspired by Sixties Motown and the group Martha and the Vandellas. In addition to this, the album also included tracks by some acts on Warner Bros. Records, namely Club Nouveau, Scritti Politti and Michael Davidson. Commercially unsuccessful and unknown in the US, these groups needed a platform to project their songs, and including them in a Madonna album seemed like the right thing to do for Warner. Two tracks by Duncan Faure and Coati Mundi were included on the soundtrack at the request of Madonna since they were her friends. Despite her only performing four of the nine tracks on the album, Who's That Girl was marketed as a Madonna album, with only her face and name appearing on the cover art.
