Holy shit. Arguably the best girl group out there, Fifth Harmony, just released their best song yet. It's even better than the criminally underrated "BO$$." It's called "Sledgehammer" and you need it on your fall playlist immediately.
Listen. Share. Buy "Sledgehammer" on iTunes because it's not on Spotify yet (fml).
