Fifth Harmony releases their single Sledgehammer. The single is the second single off their debut album Reflection. The song is a collaboration of writers Jonas Jeberg, Meghan Trainor and Sean Douglas. Camila Cabello:
It’s cool because we’ve never released a single that’s about love — a happy, cute love song. It’s about being with the person you like and feeling the beating of the heartbeat that beats like a sledgehammer.
