Lady Antebellum, one of country music's biggest success stories of the last two years, is on a roll. Need You Now, the first single from the trio's forthcoming second album, is the Hot Shot Debut at No. 50 on Billboard's Hot Country Songs.

The track speaks to anyone who has broken up with someone and regretted it in the early morning hours: It's a quarter after one, I'm a little drunk and I need you now. Members Hillary Scott, Charles Kelley and Dave Haywood co-wrote the song with Josh Kear.

Lady Antebellum's 2007 debut single, Love Don't Live Here, reached No. 3 on Hot Country Songs. The group scored its first No. 1 with its third single, I Run to You, in July. (Its second single, Lookin' for a Good Time, reached No. 11 on Hot Country Songs in 2008.)

The trio's self-titled debut has sold 751,000 copies, according to Nielsen SoundScan, and the group won top new artist awards in 2008 from the Country Music Association and the Academy of Country Music.

Kelley says the group, which is co-producing its second album with veteran Music Row producer Paul Worley, is spending more time on arrangements than it did on its first album. Hopefully people can hear that on 'Need You Now,' he says. We're trying to get a little more creative on intros and outros. We've been able to take our time with this one. We've tried to analyze the songs from a lot of different directions.

We've been dying to get back in the studio, Kelley adds. It's a different kind of artistic creativity; it's constructing something as opposed to entertaining.

The group toured with Kenny Chesney and Keith Urban this summer and also headlined some of its own fair and festival dates. It's been awesome, Kelley says. We're finally seeing that there's an awareness of who we are and our music. We look out in the crowd and we're seeing more and more people singing our songs.

That stands in stark contrast to shows the trio did in 2008, Kelley says. For the most part, the majority of the audience had no clue who we were last year. It's pretty wild to see it move in baby steps, a little bit at a time. Hopefully it's just the beginning.
