It's do-or-die time: Home Free are one win away from securing a spot in the Video Shootout Hall of Fame for their “Good Ol’ Country Harmony” music video.

Last week, the country a cappella group bested Jana Kramer‘s “Said No One Ever” and Kenny Chesney‘s “Noise.” Looking for their fourth and final win, Home Free are competing against Brandy Clark ("Girl Next Door") and Martina McBride ("Reckless"). Fans can watch all three of this week's competing clips below.

Will Home Free earn that Hall of Fame spot? Or would you rather see Clark or McBride advance? Vote as often as once per hour in the poll below, which closes on Monday night (May 30 -- we're giving you an extra day due to the Memorial Day holiday!).

Video Shootout Rules: The video that receives the most votes wins, and the winner goes on to face two new challengers in the Video Shootout next week. Vote as often as once every hour. Any video that wins four Video Shootouts in a row will be retired into The Boot’s Video Shootout Hall of Fame to allow new clips to compete. Certain videos may be considered for a second Video Shootout.
