As others have said, there is country music, and there is country music. One will earn you money when proformed by rock stars who want to wear a big hat, boots, and pretend they can ride that horse. (the lasso is an artist addition)

Then there is country music that the coyboys sang, or would sing today. If you want to write this style (and I encourage it, I love it enough that one song in this style a week makes me willing to wade through all the junk called country on the radio) you need to live. Get a job as a farm hand. Accually drive an old pickup truck, and make sure that you normally have it loaded it down with cargo. (at least once break the springs from the mass) Make sure at least one major component is broke. Starting via hot wiring is good. Learn how to fix a fence. Stand up your date friday night cause your standing knee deep in a manure pile with the vet trying to breech birth a calf. Then break your promiss to play the organ at church sunday morning cause doing the same in your sunday best. Oh, and learn to play fiddle, real country music has a fiddle part. :)

If anything in the second paragraph doesn't hit close to home, you don't have the expirence to write country music.

Many of my favorite country tunes are in mudcat. If the song your thinking of writing can't be included in mudcat, it falls into the first, psudo country catagory.
