Lady Antebellum, 'Hello World' -- New Song

Lady Antebellum remind us what we are living for in 'Hello World,' the country trio's fourth single off their chart-topping album, 2010's 'Need You Now.'

Under Dave Haywood's melodic piano and Hillary Scott's backup vocals, Kelley shines on this faith-infused track -- as he sings of hope and purpose in life: "Sometimes I feel as cold as steel / I'm broken like I'm never going to heal / I see a light, a little grace, little faith confirmed."

Penned by Tom Douglas, Tony Lane and David Leen, this gorgeous ballad follows their hit singles, 'American Honey,' 'Our Kind of Love,' and the genre-bending pop song 'Need You Now.'

Check out their live performance of the tune on AOL Sessions, and tune into AOL Radio's New Country First station to hear the track.
