Tim, Taylor & Keith handled the Zac Brown Band in last week's K-LAW Country Song Showdown. There are some awesome harmonies involved in this week's matchup. We're featuring the new song from Lady Antebellum, 'Goodbye Town', and Little Big Town's latest effort, 'Your Side Of The Bed'. Three-part harmony vs. four-part harmony. They're both great songs, but only one can win this week's Showdown. Watch the videos below, then vote for the one you like the best. Voting will stay open until Monday night, June 10th at midnight.
