That's the stereotype of Country Music, but believe me, that is just a very small part of it. I've been a Country Music DJ, air personality, on the radio for 25 years and you would be hard pressed to find a more pro-American style of music than Country.
Songs about our troops, America, and average American life and love (read: fly-over country) in general are the norm in this great music format.
Country Music has its roots in the Irish-Scots hill music of Appalachia the 1700s and spawned Rock n Roll in the early 1950s. Think of Elvis, The Hillbilly Cat, as he was known in 1955.
Yep - I’ve been listening to it, on and off, for nigh on to 50 years.
