Magan Traynor has a lot of good songs about being powerful as a woman, but I'm not sure how her voice would be to you.

As for deep voices, the first one that springs to mind for me is Josh Turner. Sam Hunt has a pretty deep voice, too, and his stuff is pretty decent. )We like both, if that means anything)

Ima think barry manalo be Okay for ye, too, but I can't bve rememberin' if his voice be deep while singin' or not.-C

Leonard Kowen is another, but he's a bit darker in content sometimes, so you may have to be in the mood for him.-T
