For the second consecutive week, Brett Young’s “Mercy” is No. 1 on both the Billboard Country Airplay chart and Mediabase chart.

The breakup ballad, which was co-penned by Brett and Sean McConnell, features simple piano accompaniment with Brett’s stripped-down vocals that beckon his love interest to end their relationship with “mercy.”

“Thank you to the best fans in the world and country radio for supporting this song,” Brett said. “From the beginning, your response to ‘Mercy’ has been overwhelming in the best way possible.”

“Mercy” follows previous chart-toppers “Sleep Without You,” “In Case You Didn’t Know” and “Like I Loved You” from Brett’s 2017 self-titled debut album.

“Falling in love or falling out of love—those are the easiest songs to write because it’s just straight from personal experience,” says Brett to Nash Country Daily. “I think everybody’s felt both of those. Everybody’s been in love, everybody’s had heartbreak. We noticed that when we put together the 12 songs that would make the [self-titled debut] record, there was not a party song on this record. I’ve written a ton of party songs and not that there’s anything wrong with that. I think, in trying to tell my story and let people get to know me, it seemed like we should talk about things that I’ve lived.”

Brett will release his new single, “Here Tonight,” in September. The tune will be the first taste of his upcoming sophomore album, which is tentatively slated for release in late 2018.
