Lady Antebellum are sitting pretty at No. 1 on the country singles charts with 'Our Kind of Love,' but they are already plotting for their next hit off their double-platinum-selling 'Need You Now' album. The country trio releases the spine-tingling ballad, 'Hello World,' this week.

"I don't think we've ever been more excited about putting a song out to radio as we are now," Lady A's Dave Haywood tells The Boot. "We believe so much in this message and so much in what this song says. We heard this song on a Friday before we were recording on a Monday to cut the album. We were right at the very end, and we were thinking to ourselves that we really wanted to have a song that had a positive message and something that will help give people hope on our CD. We didn't feel like we had that yet."

Bandmate Hillary Scott made a suggestion that would change Lady A's "world." "Hillary had this song on her iPod," Dave recalls. "Someone had given it to her two or three years ago when she was going through a little bit of a rough time. She was like, 'This song gave me a lot of hope during this time in my life ... It's just something I leave on my iPod because it gives me hope when I'm having a bad day.' She played it for us, and it was literally a piano and [songwriter] Tom Douglas' vocal on it. Tom wrote the song with David Lee and Tony Lane. It almost brought all three of us to tears. We knew that's the song that we were looking for. That's what we wanted to say and be affiliated with ... that kind of message."

When Lady A brought 'Hello World' into the studio, all three members were blown away by the powerful life it had taken on. "We felt so great about the arrangement we came up with," notes Dave. "I think that Charles [Kelley's]' vocal is impeccable and flawless on it. When the album came out, everybody would ask us what's our favorite song on the album. It has always been 'Hello World.' It's an incredible song. I'm happy that we could be the voice to get that message out there."
