Nashville, my first trip to the ville of the nash

I'm actually excited because in March 31st I'll be flying towards Nashville in what will constitute my first business trip as we'll be attending a steel convention there.

Anyways, I'll have some time off the first few days and then work the last few days, yeah, I'll only be there a few days. I'm scheduled to return on a saturday, is it worth to stay there the extra day?

Any tourist tips? Any info is appreciated.
