I used to really like country music, but have pretty much fallen out with it since the 90's.  Do you like it?
yes, I like it.  It orginated in the United States in the early 1920's
I liked Garth Brooks a lot back int he day.  Then more moved into "texas" country
I used to like him too.  country music takes its roots from genres such as folk music and blues
Yes, you can hear it for sure the older the music is.  It seems like nowadays it has gotten much much more pop and much less blues and folk.  Except for maybe a few.
yes, it consist of ballads and dance tunes with generally simple forms, folk lyric and harmonies
