Well, there isn't a single Brooks and Dunn song that I don't know all the words to, but my favorite song to sing to that I definitely know all of the words to would have to be "Country Boy" by Aaron Lewis (lead singer of Staind). I first heard this song about a week ago and I immediately fell in love with it. I have listened to it so many times in such a short period I'm not surprised I've already remembered all the words to it.
"And I like my jeans and my old t-shirts...
...and a couple extra pounds never really hurt."
