It was probably because there were some real gems on there. Their latest, "Cheat On You", being one of those gems ("That's Why I Pray" and "Can't Be Satisfied" being the others). It shows just why we all (occasionally) love Big & Rich.
The production is mainly acoustic, with some electric guitar thrown in. It does a good job of not
overwhelming B&R's near perfect harmonies.
It's well written, and will be easily relatable for many people (not to mention the video is great).
Though it's all really great, the peak of the single, is the bridge. I'm not quite sure why, but there is something about that seems great to me.
One last thing. It's amazing how much more I like their voices when they're together.
Career highlight for the duo.
