I am personally a huge fan of Steve Grand and have spent far to much time listening to All American Boy. Though I adore his song Back to California.
Check him out, though be warned, he is an openly gay singer, in case that's not your thing.
For more traditional country music I like
"I Drive Your Truck" by Lee Brice. I never fails to make me tear up.
"Georgia Clay" by Josh Kelley
"American Solider" By Toby Keith
"Courtesy of the Red,White,and Blue, also called The Angry America" by Toby Keith
"Bullets in the Gun" Toby Keith
"Arlington" by Trace Adkins
"Fly over States" By Jason Aldean
"Where I'm From" By Jason Michael Carroll
"If your reading this" by Tim Mcgraw
"God Bless the USA" By Lee Greenwood
And what horse girl doesn't love.
"Girls and Horses" By Templeton Thompson
"Cowgirls Don't Cry" by Brooks and Dun.
For not super country like I love
"Two Black Cadillacs"
