The Grammy Song of the Year category honors the unsung heroes of the music business -- the songwriters.

Of the five songs nominated, only two of them were co-written by the artist who sings them -- Eric Church's "Springsteen" and Ronnie Dunn's "Cost of Livin'.'"

Here's a rundown of the Country Song of the Year nominees and the writers up for the award:

• "Blown Away" - Josh Kear and Chris Tompkins, songwriters (Carrie Underwood)
• "Cost of Livin'" - Phillip Coleman and Ronnie Dunn, songwriters (Ronnie Dunn)
• "Even If It Break Your Heart"- Will Hoge and Eric Paslay, songwriters (Eli Young Band)
• "So You Don't Have to Love Me Anymore" - Jay Knowles and Adam Wright, songwriters (Alan Jackson)
• "Springsteen" - Eric Church, Jeff Hyde and Ryan Tyndell, songwriters (Eric Church)

The Grammy Awards will air live Sunday at 7 pm on CBS.
