I never listened to Hootie much, but as others have said, Old Crow did "Wagon Wheel" much better. For me, the two or three country songs I've heard Darius sing are missing something... some spark, some energy... It's something about how he delivers the lines to his songs that, for me, comes up short of making his music interesting. I can't quite put my finger on it, because his songs aren't terrible. The instrumentals seem solid, and the lyrics are good, he hits the notes, but something about the way he sings them just doesn't make me want to listen to them for some reason.
On the other hand, my wife thinks he's a good singer and enjoys his songs.
If you see Hobbes, tell him I said "Hi".
