Rhett Akins has had his share of hits on his own, but in the late ‘00s he started concentrating on penning tunes for other singers, piling up more hot singles than ever. In his role as unstoppable hit machine, Akins became known for his country duality. One minute he'll pen old-school-sounding cuts like Thomas Rhett's twang 'n' bang drinking song "Drink a Little Beer," then the next he'll turn around and write an utterly of-the-moment track like Blake Shelton's hip-hop-inflected mega-smash "Boys 'Round Here."
