In the last twelve months, rising country music star Kacey Musgraves has been on a roll in the music world. Just last week at the Music Row awards she won “Breakthrough Songwriter” for writing her top 10 debut single “Merry Go’ Round” and “Mama’s Broken Heart,” which has become a number one hit for Miranda Lambert. She also received honors for “Breakthrough Artist” and “Song of the Year” for “Merry Go ‘Round.” The Nashville beauty is now lending her voice to OREO cookies, as part of the OREO ‘Wonderfilled campaign’ – which celebrates the significant impact the simple act of sharing an OREO can have on your day. The ad spot is slated to launch on national TV starting July 8. Keep an eye out on CMTT for the commercial.
