Who've I been obsessing with lately? Jack White. His voice. I can pick it out of any of his songs, even if he just has a little vocal part. If you don't know 'bout him, here's a little info.: He's mostly known for 'The White Stripes', 'Raconteurs', 'The Dead Weather', and his newest solo album 'Blunderbuss'.
I love his rock vibes he gives off, but if you dig a little, you hear the blues. Give him a try. Also, you'll love this music video, if you have a since of humor:
