At over 20,000 square feet, this home in Nashville is almost big enough to host the CMA Music Festival this summer. All that space sprawls out on six well-manicured acres of land. And it's owned by a country music superstar -- or at least, that's what we're led to believe. Do you think you know who lives here?

The property is currently for sale at $19.5 million, which is more than double its 2009 market value. Inside you'll find that no expense was spared on flooring, hardware or furniture. The hallway screams castle, while the 432 square-foot master bedroom bleeds luxury. Six bedrooms, eight full bathrooms and three half baths make this place the most palatial of all homes we've seen.
