Destiny's Child's album cuts allow them to dive even further into R&B's next wave. “Happy Face” rides skittering castanets to dance-floor euphoria; Timbaland's rework of “Say My Name” places Beyoncé's voice atop skeletal, yet sensuous funk; and the gently sympathetic “Sweet Sixteen” calls back to the Mahogany era while foreshadowing the strummy soul that Beyoncé would perfect years later on “Irreplaceable”.
