Rascal Flatts are here to let you know that they've got your back on 'I Won't Let Go,' the second single from their 2010 album 'Nothing Like This.'

Lead singer Gary LeVox sings in a plaintive, vulnerable voice over delicate piano chimes as the song begins in a manner recalling Bette Midler's 1979 classic 'The Rose.' The song steadily climbs into familiar, uplifting mid-tempo power ballad territory as the listener is assured of true friendship in the face of adversity:

"I will stand by you / I will help you through / When you've done all you can do and you can't cope / I will dry your eyes /  I will fight your fight / I will hold you tight / And I won't let you fall."

'I Won't Let Go' seems certain to follow the album's first single, 'Why Wait?' into the upper reaches of the country charts. You can also undoubtedly catch the trio performing the song live all across the country next year as they embark on their massive 2011 tour, which kicks off Jan. 14 in Sioux Falls, S.D.
