Brett Young's "Mercy" is an original plea for an ex-lover to leave him the heck alone. The singer says it's a song based on a true story, one that his fans relate to.

“Every time we’ve played it out it’s all people want to talk about after the show and I think the reason is it’s about going through a breakup and having that person kind of just continue to poke their head in their life and not let you move on,” he says.

A former flame inspired the song. In fact, it's the same person who inspired many songs on his debut album, including "You Ain't Here to Kiss Me." She kept coming back around in subtle ways, and it was torture on his heart ...

“I think everybody knows that feeling," Young says. "Like ‘If you’re not calling me because you want to get back together, then quit calling me.’”

"So if you're gonna break my heart, just break it / And if you're gonna take your shot, then take it / Take it / If you've made up your mind, then make it / Make this fast / If you ever loved me / Have mercy," he sings at the chorus of "Mercy," the fourth single from Brett Young.

Slow, delicate, but intense love songs are Young's specialty on his debut album. The California native has a sensitive soul. He always has.

"The same kid that was writing poems in his text books in high school, I'm still that person," Young tells Taste of Country. "Mercy" follows up back-to-back Billboard Country Airplay No. 1 hits in "Like I Loved You" and "In Case You Didn't Know." Young was part of the inaugural class of Taste of Country RISERS.
