I was where I was when I made my first album." "Rebirth" predominantly consists of dance and hip hop music, while also incorporating '80s pop-rock. Lopez was influenced by James Brown's music when creating "Rebirth". The album opens with the song "Get Right", an R&B, dance-pop and funk-influenced song written by Rich Harrison, which contains heavy horn instrumentation. The song was originally recorded by Usher with the title "Ride" for his album "Confessions", but was scrapped. "Step Into My World" contains African music influences, and is sung by Lopez through a breathy vocal. "Hold You Down" is a "mellow" R&B song which features Fat Joe. It samples Shirley Murdock's "As We Lay". The track was a "last minute" add to "Rebirth". Lopez recruited Fat Joe for the song because it was a "friendship record", and she didn't want to do it with anybody else. He said, "We don't talk every day, but we got mad love for each other whenever we see each other. It's always crazy love." "Whatever You Wanna Do", also written and produced by Harrison, makes use of drums and horn instrumentals. "Cherry Pie" is an uptempo pop-rock song which features drums and an electric guitar; Lopez describes the song as having a "Prince vibe". "I Got U", written and produced by Jerkins, lyrically speaks about her secretive relationship with Anthony, with lyrics such as "Sometimes real love can be not seen 'cause you're thinking what's right in front of you can't be the one for you." "Still Around" is a summer-influenced R&B song which lyrically speaks about undying love. Anthony makes a spoken appearance in the track. "Ryde or Die" is an intense R&B and hip hop track which was co-written by singer Brandy for 2004 album "Afrodisiac". The song was later given to Lopez who recorded it, with Norwood singing background vocals. "I, Love" is a mid-tempo song which contains staccato percussion and airy synths. The song's lyrics have Lopez convincing her lover that she cares about him, and that their chemistry isn't "pretend" or "make-believe", with her even stating that she'd die before hurting him. "He'll Be Back" and "(Can't Believe) This Is Me", the album's final tracks, have been said to address lingering issues in Lopez's own love life.
