I always sing with an accent, it's just how I sing. You've heard my Irish & Scottish accent...I've had people think I was from there. I even find myself, in general conversation, slipping into the accent and pronouncing things with that accent. Most people DO sing with an accent, even Americans from the midwest. Check out the band Counting Crows. They sing with out any accent. It sounds really bizarre. Mosrt of you wouldn't like it.
