Keith Urban is excited to perform at Sunday's (Apr. 7) ACM Awards, but he won't be delivering one of his current or upcoming singles. Rather, the singer explains on social media that he's going to try something different.

"I'm going to be doing a song tonight that is something I heard recently that absolutely spoke to me," he says. "I just love this song."

He notes that the song is not his next release, but is simply "just something I really wanted to do tonight."

Urban gives similar details on the ACM Awards' Instagram, with a bit more information: The song is, apparently, titled "Burden"—and Urban claims it will stop fans in their tracks—but that's all we know about it for right now! "I hope you like it," Urban says, with a smile.

Urban is up for Entertainer of the Year and Male Artist of the Year at this year's ACMs. He's been nominated in the Entertainer of the Year category a whopping eight times, but has yet to win that particular title. "I know what the bridesmaid feels like," he jokes, adding that he's just pleased to be nominated.
