A lot of good ones. Some, like Alicia Keys are great artists but they are far too young and it is far too soon to judge them in this category. Also, unlike several of the other young artists/bands, she didn’t break through any musical barriers or achieve any major milestones (like Mariah beating the Beatles number of gold records).
I’m not saying she isn’t a great artist.. it is just too soon for her to be on this list.
I think she had her first number one twenty-years ago this year. Just saying. I don't really care for her music, but this isn't her first rodeo.
