 After "Sometimes" is ... Baby One More Time's fourth track, "Soda Pop", a song that draws influences from bubblegum pop and dancehall, and features background vocals from co-writer Mikey Bassie. Spears' vocals on the fifth track and fourth single, "Born to Make You Happy", span more than an octave. Its lyrics allude to a relationship that a woman desires to repair, not quite understanding what went wrong, as she comes to realize that "I don 't know how to live without your love / I was born to make you happy". The sixth track and final single, "From the Bottom of My Broken Heart", is a sentimental slow-tempo teen pop ballad. "I Will Be There" features a guitar riff similar to Natalie Imbruglia's "Torn" (1997), with a "rousing chorus about standing by your man (or a best friend or a house pet)", as noted by Kyle Anderson of MTV. The eleventh track, "E-Mail My Heart", is a sensitive piano ballad where Spears sings, "E-mail me back / And say our love will stay alive". The cover of Sonny & Cher's 1967 single "The Beat Goes On" is influenced by bossa nova and trip hop, and features a similar sound to spy movies themes.
