Arista's JP Saxe has a new single with Maren Morris, "Line by Line." Written in Nashville, the song was penned by Saxe, Morris and "The Bones" co-writer Jimmy Robbins.

The new collab and accompanying clip (below) arrive ahead of the 63rd annual Grammy Awards, where Saxe is up for Song of the Year for his 2020 smash "If the World Was Ending" f/Julia Michaels. 

Saxe stated that it was "surreal" to share the song with one of his "favorite artists ever." Morris revealed, "Writing that day with JP was the most fluid, inspiring session. He’s a lyrical faucet. He threw out the line 'immortalizing my sincerity' and it blew my mind. I think all in all, we wrote the whole song in an hour and immediately recorded it."
