In a press release she reflected on her second album and said, "Hip-hop was taking over at the time, but I was fighting to preserve the bridges, melodies, and harmonies that have always been at the heart of R&B. The goal was to blend those two worlds through the art of sampling. I loved the minimalism of a beautiful vocal arrangement over a simple drum loop or a classic guitar like 'Irreplaceable'…but only if that 808 was banging underneath."
