Sara Evans' latest single 'A Little Bit Stronger' is already on the charts -- though that's no huge surprise, considering it was touched by the hands of both Evans and Lady Antebellum's Hillary Scott, and featured in the movie, 'Country Strong.'

Evans tells Taste of Country that she is "overjoyed" by the song's success, because she didn't know what to expect going in. "You know, I was a little nervous because it took me a long time to make this album and just didn't know what the response would be to me after taking that time, you know, sort of down -- or away from radio," she says with a sigh. "So the fact that it's doing great, and you know, the sales on the single ... is just what's overwhelming all of us. We're so pleasantly surprised, so I could not be happier right now."

Evans says she was drawn to the song for the same reasons we were -- love, and great lyrics like these, which describe the painful feelings of letting go of a bad relationship:

"I know my heart will never be the same / But I'm telling myself I'll be okay / Even on my weakest days/ I get a little bit stronger."

'A Little Bit Stronger' is a glimmer of positivity, a reminder that there is life after love. Evans echoes that the song is relatable and strong enough to carry itself well, which is what she felt on first listen. "I loved it. When you hear a song and you love [it] and you can't explain why -- I just thought it was a great lyric and a great melody," she says of the single, written by Luke Laird, Hillary Lindsey, and Hillary Scott.

"Hillary [Scott] had recorded a great demo of it and she represented the song so well. It struck a chord with me, and apparently it's striking a chord with a lot of people just going through a hard time and coming out on the other end stronger," she adds.

'A Little Bit Stronger' has sold over 350,000 digital copies to date. Sara's new album, 'Stronger,' debuts on March 8.
