John Meyer (although I think he should dump Jessica Simpson...there's a heartache waiting to happen...can you say serial dumper or latching her nails into the next rising star)?
Embarrassingly enough, I don't follow the music scene to know any new artists. I usually don't hear about them until they've released a dozen albums and everybody's talking. Then I check them out.
The group that I like that is newest to me right now is Celtic Woman.
I have heard Celtic Women and I would agree I thought they were very good. Other than that I really don't have any favorites that stickk out at the moment.
