John Mayer?!

The bluesy music style maybe--but I think it's more of a Motown sound. His voice is much more raspy than John Mayer. His voice is more of a Rod Stewart sound.
Personally, I like him! I like the raspy, Rod Stewart-type voice and I REALLY dig the Motown style sound he has.
I have his 2 albums "Songs for you..." and "Undiscovered".
