The 2015 CMA Awards are so close, and there are a slew of country stars vying for awards -- but only one will emerge the winner in each category. For Single of the Year, the trophy is awarded to the artist and the producer, and with a stacked selection of songs receiving nods this year, the competition is tight.

Kenny Chesney's "American Kids," produced by the singer and Buddy Cannon, is full of ingenious wordplay, incredible hooks and a deeper message about all the good moments in life. It soared to the top of the iTunes Country Songs chart two days after its release.

Of course, Little Big Town's melancholy "Girl Crush," produced by Jay Joyce, received a deserving nod for Single of the Year. Despite the controversy it raised upon its release, the tune went on to crush a long-standing chart record, and "Girl Crush" stands out as one of the most unique "jealousy" songs that's ever been recorded in country music.

Lee Brice wrote and produced the ever-sweet hit "I Don't Dance," which already garnered him Single Record of the Year at the 2015 ACM Awards. Written for Brice's wife, "I Don't Dance" is a song that many fans have come to love.

Zach Crowell and Shane McAnally produced Sam Hunt's “Take Your Time," from his freshman Montevallo album. It's not your typical country song -- Hunt's R&B influences are prevalent -- but that's what makes Hunt stand apart from other artists. Plus, "Take Your Time" received Taylor Swift's stamp of approval.

Eric Church's "Talladega" was co-produced by Joyce and Arturo Buenahora Jr. It's the singer-songwriter's second No. 1 song from his Grammy-nominated album The Outsiders. The tune is a commentary on life, taking a nostalgic look back at some of Church's favorite memories.
