10. Luke Bryan, "Roller Coaster"
Set in Panama City Beach, Florida, this sun-kissed song about a short-lived courtship takes you through the peaks of young love and valleys of finite goodbyes. "She's like a song playing over and over/In my mind where I still hold her/I had the chance, and I should've told her," Bryan sings with pain in his voice as the lyrics take a sharp turn from romance to regret. CMA-nominated newcomer Cole Swindell co-wrote this tune back when he was a merch salesman for Bryan, teaming up with the country superstar's guitarist, Michael Carter. When Bryan first heard Swindell's demo, he predicted his employee would be getting a record deal — a forecast that proved true just two years later.
