Ed Sheeran was totally “geeking out” over the opportunity to record a song for the soundtrack to Peter Jackson’s “The Hobbit: The Desolation of Smaug.”

Sheeran wrote “I See Fire” for the end credits of the movie, which is due out on December 13.

His first solo track released in two years gave him the opportunity to produce the song and play all the instruments, including picking up a violin for the first time.
