Rock is obvious. Though I do like country and rock if it is blended right. For example, the Desperado album by Eagles is a joy to listen to. I can play it over and over. CCR also did a good job with it.
Country is standable. It's just some songs I just cant stand... I'm more of a rocker. A classic rocker ('50s~'80s). I can't stand all that heavy rock crap.
