I really enjoy listening to country music. It's a musical genre that started out in the south U.S. in the 1920's. 
once in awhile i like to listen to country music
It's roots come from folk music, especially Appalachian folk music) and from blues.
its a very american type music
In 2009, the most listened to genre during rush hour traffic was country music. It was also popular during the morning commute.
i can see that, the music is very consistent while pop and rock changes over time
That's very true! It often consists of dance tunes and ballads with generally a simple form. They are string instruments too like banjos, electric guitars, and steel guitars.
i enjoy more the instrumental type country music than the others
