Miranda Lambert's hit record 'Mama's Broken Heart' is one of the hottest songs in country music. It appears on Lambert's latest CD, 'Four The Record', and is an in-your-face, rocking country tune delivered with tons of attitude we've come to expect from Miranda. But did you know 'Mama's Broken Heart' was co-written by Kacey Musgraves?

Kacey recorded her own version of the song Miranda is currently making famous, and it's a very different - but equally excellent - rendition. It's a more melodic interpretation, loaded with mandolin and a much more acoustic feel. Take a listen here.

As much as I enjoy Miranda's rocking interpretation, I love how the Musgraves version keeps a country edge. What do you think?

Kacey's version doesn't show up on her new CD, 'Same Trailer Different Park', and there's no telling if it will ever make an album.

The praise keeps coming in for Musgraves, who is currently on tour with Kenny Chesney. Southern Living is calling the East Texas singer/songwriter "The next big thing". Rolling Stone Magazine has her as an "Artist to Watch". And her feature on CBS "Sunday Morning" boldly states that she is "taking country music to new horizons".
