"Blue" by Beyoncé feat. Blue Ivy
Featured on Beyoncé's eponymous fifth album, "Blue" is the singer's lovesong for her daughter. Released a year after Blue's birth, the song features home-shot videos of baby Blue with her parents, as well as the toddler's own voice at the end of the song. "Hold onto me, hold on," she sings, copying her mother before dissolving into giggles.
