The way it expresses subtle emotions:
Joey + Rory, "Cheater, Cheater"*
I think the errors add a certain je ne sais spelling.
Danielle Peck, "I Don't"
Not the greatest song ever, but with one of my favorite lyrics of all time in the chorus.
Speaking of which. . .
Hayes Carll, "She Left Me For Jesus"
All of which, of course, just leads me back to a classic:
Mary Chapin Carpenter, "The Bug"
Have to say, never really thought of Xena when I heard that song, but I'm sure I will now.
