With the threads about Cat Stevens and Johnny Cash, I started thinking about creating this thread. I'm talking about popular music, which while I'm not saying C&W isn't popular, I'm not including it in this poll. In fact, I'm having a hard time limiting my choices to a reasonable number. But I'm making it multiple choice, so select which performers are your favorites out of these choices. For the same reasons I'm not including Michael Jackson. This is basically about rock groups who dominated the airwaves from the 50's until now.
