Sugarland, "Stuck Like Glue"

Jennifer Nettles and Kristian Bush of Sugarland are poised for a whopping pop crossover with "Stuck Like Glue," which has already achieved the chart milestone of highest Billboard Hot 100 debut (No. 20) for a country duo or group. Co-written with Better Than Ezra's Kevin Griffin and songwriter Shy Carter (Rob Thomas' "Someday"), the song features Bush's brother, Brandon, on accordion and creates a Southern comfort vibe with mass appeal. It also taps into the rising trend of reggae-pop-from Jason Mraz's "I'm Yours" to Train's "Hey, Soul Sister" and Travie McCoy's "Billionaire"-that offers a refreshing alternative to the dance-pop hits dominating the airwaves. The song's catchy lyrics should keep "pulling you right back in," and you'll probably tap along to its beat, too.
