“Sledgehammer” is the third track and second single of Fifth Harmony’s debut album, Reflection. In this electro-pop track, the group compares the visceral side of a crush to being hit with a sledgehammer.

As many fans noted, Dinah didn’t have a solo part on this song. According to her, it was because the producers felt her voice wasn’t suited for pop. This also happened in 5H’s previous single, “Bo$$”.

The song peaked at number 40 on US Billboard Hot 100 and was certified Platinum in the US.
