During the 2000s, there was no bigger act in country music than Rascal Flatts — and, for a time, there was no bigger group in America than the cheerful country-pop trio from Ohio. At their peak in the middle of the decade, Rascal Flatts were the top-selling group in America, besting rock bands and hip-hop crews because they consciously made music that appealed to a variety of demographics. While they anchored themselves in country, their music was soft enough to cross over to the adult contemporary pop charts, muscular enough to fill arenas, and flexible enough to change with the times.
