[EX Q]: Question: Was Brandy's co-star in Double Platinum older than 50 at the time? Passage:"Learn the Hard Way" is the album's fourth track. It is the third song on the album, and shares similarities with the song "Never Say Never". The Guy Roche-produced "Almost Doesn't Count" is the fifth track. Brandy performed the song in the 1999 film Double Platinum, starring Diana Ross and herself. The international single "Top of the World" is the album's sixth track. It is a collaboration with Mase and the song talks about Brandy as a popstar just trying to be her and not feeling like being in her own world. In the music video, directed by Paul Hunter, Brandy was featured incurring various supernatural phenomena. She spontaneously floated in the air, flipping and somersaulting above random objects; telephone poles and vehicles, as people stopped to stare. These strange phenomena also included balancing herself vertically and horizontally alongside skyscrapers and buildings. The Darkchild-produced "U Don't Know Me (Like U Used To)", which is the album's seventh and final single, is noted for its remix version with Shaunta and Da Brat. The remix was released as the lead single to the same-named EP. "Never Say Never", also produced by Rodney Jerkins, is the eighth song of the album. "Never Say Never" was released as a Germany single in 2000. "Truthfully", a ballad about a broken relationship, was penned by former Boyz II Men member, singer-songwriter Marc Nelson. Recorded in a single take, it took Nelson five different sessions to get Norwood in the recording studio as she felt initially nervous about working with him. Main production on the song was helmed by Harvey Mason, Jr. who received his first major placement as a producer on "Truthfully". Mason was consulted by Jerkins after he had shopped around several tracks for record executives.
