Flirting with pop, rock, folk, funk, R&B, even classical music, this Colorado band offers one notable constant: an undeniably killer hook. Oh, and drama—plenty of it. It's all built on Ryan Tedder's soulful croons, which fluctuate with every passing mood, as he quivers through jilted pain on the cello-touched piano ballad "Apologize", unleashes a slick falsetto over the sweeping synth-pop of "Kids", and rhythmically rivals the rousing, hand-clapping folk of "Counting Stars". But OneRepublic's greatest triumph? That just might be bringing Bach to stadiums worldwide with pop anthem "Secrets".
