13. Kristian Bush, "Trailer Hitch"
"Wait…you can sing?" That's a question Sugarland guitarist Kristian Bush heard a lot in 2014, as he released his first solo single, which finds him center stage for the first time since the group's inception more than a decade ago. The surprise is a pleasant one, as the Tennessee native's vocals on "Trailer Hitch" are an engaging mix of rock-influenced grit and country soul. But what really stands out in Bush's solo introduction is his affable personality, which is reflected in the happy-go-lucky lyrics. Co-written with his brother Brandon Bush (of Train) and Tim Owens, the song celebrates the joys of giving, which far outweigh the jollies of material possessions. The hook: "You can't take it with you when you go," he sings. "Never seen a hearse with a trailer hitch."
