Fifth Harmony are delivering yet another harmonious cover. This time the 'X Factor' alums performed a piano-driven rendition of 'Red' by Taylor Swift.Swift's music seems like a perfect fit for the five ladies, as they've already covered tracks by the country crossover's ex (One Direction's 'They Don't Know About Us') and current tour mate (Ed Sheeran's 'Lego House'). This version is much slower and more emotive than the original -- and vocally speaking, more is truly merrier. We may even like it better than Swifty's!
