Following the Rick Rubin-produced “Bloodstream,” Ed Sheeran debuts his most tender tune yet off his upcoming album x. The 23-year-old singer celebrates an everlasting love on the soulful guitar ballad “Thinking Out Loud,” which is destined to become a wedding anthem.

“Darling I will be loving you till we’re 70,” sings Ed. “Baby my heart could still fall as hard at 23.”

Due June 23, x also includes the Pharrell-produced “Sing,” plus production from Rick Rubin and Jeff Bhasker.

Listen to his sweet serenade below.
