Sheffield, Rob (8 juli 1999). ”On the 6; Album Reviews”. Rolling Stone. Jann Wenner. http://www.rollingstone.com/music/albumreviews/on-the-6-19990708. Läst 8 april 2013. Originalcitat: "Instead of strained vocal pyrotechnics, Lopez sticks to the understated R&B murmur of a round-the-way superstar who doesn't need to belt because she knows you're already paying attention [...] She makes a little va-va and a whole lot of voom go a long way."
