If you haven't already heard Garth Brooks' most recent single, 'Mom,' it won't be that way for long. The song is the most-added single at country radio right now.

The song had 51 Mediabase Country adds on Nov. 24, and it's easy to see why: The song is a tearjerker, playing through a conversation between God and an unborn child. And the fans aren't the only ones who have shed a few tears while listening to Brooks' second single from 'Man Against Machine;' the singer admits to crying at it himself.

“When God describes what a mom is, I weep uncontrollably every time,” Brooks says. “Is there anything more beautiful than [a] mom to pay tribute to?"

The country legend debuted 'Mom' on 'Good Morning America' earlier in November.

"Everyone knows how much I loved my mom," Brooks says. "Why no one has ever written this song before, I don't know. Why I never wrote it before, I don't know, but I'm grateful Don Sampson and Wynn Varble did.

"It took me almost a month to get it together to record it," he adds. "My producer finally told me to man up and do it."

'Man Against Machine,' Brooks' first album in 13 years, debuted at No. 1.
