"Stuck Like Glue", Sugarland's bubbly 2010 crossover hit, seems preposterous on paper: It opens with a beatboxed rhythm, adds accordion and acoustic guitar, and goes for broke with a patois-filled reggae bridge. Out loud, however, the song sounds like magic—an indelible country mélange that could come only from this Atlanta duo. Formed in the early '00s, Sugarland pushed their genre up and out, enthusiastically embracing rock, pop, and life's little pleasures. "Baby Girl" is a showbiz success story worthy of the Dixie Chicks, and "All I Want to Do" celebrates love with some perky yodeling.
