The album's opening track, "Love Don't Cost a Thing", is a Ric Wake-produced pop song, which lyrically centers around a materialistic relationship. "I'm Real", which was composed by Lopez with Cory Rooney and Troy Oliver, has a retro vibe, and was likened to music from Janet Jackson's album "Control" by "Slant Magazine". "Play" is a dance-pop track that received production from Swedish producers Arnthor Birgisson and Anders Bagge, and features back-up vocals from recording artist Christina Milian. In the track, Lopez pleads with a nightclub DJ to "play her favorite song" over a shuffling electric guitar and dance beat. "Telegram & Gazette" compared its sound to Madonna. "Walking on Sunshine" was considered a "techno-disco anthem", while "Ain't it Funny" is a Latin pop song that returns Lopez to her Latin roots. Written by Lopez and Rooney, it contains lyrics about "creating the perfect romance in your mind, then facing reality when Mr. Right is less than ideal". "We Gotta Talk" has double-time beats and, lyrically, "prescribes communication and compromise to heal a romantic relationship".
