Jim Reeves was great. I like some of Johnny Cash's stuff. I also loved Wilf Carter growing up. I associate Hank Williams with my Dad, so it's good.
I HATED Conway Twitty at first and regretted so much buying my mother one of his CDs for her birthday because I was still living at home and I had to hear it all the time. But after several months he actually started to grow on me and I like several of his songs now.
I can't stand most of today's country music. Anything twangy is unbearable to listen to.
