Thomas Rhett is DEFINITELY bigger than Rhett Akins. Rhett had one hit song "That Ain't My Truck". But Rhett Akins now focuses on songwriting with his friends Ben Hayslip and Dallas Davidson and has written a slew of number one hits now. They call their songwriting group "The Peach Pickers" and they open for Luke Bryan on his annual Farm Tour (where Luke plays big farms around the US) and play covers of all the songs they wrote, except the ones Luke sings, obviously.
I'm a huge Thomas Rhett fan. His latest record is really good.
