Lonely Lullaby

"Lonely Lullaby" is a song by American electronica project Owl City from his third studio album All Things Bright and Beautiful (2011). Originally released as a fan club exclusive in March 2011, the song is not included on the album itself. It was released digitally on July 19, 2011 through Universal Republic Records as the third single from All Things Bright and Beautiful.

Background
The song is a tribute to Annmarie Monson, an ex-girlfriend of Young's, who he describes as the "most wonderful, beautiful woman" he knew. He stated that the track was a lot more "personal" to him.

""A lot of my songs are written purely from the imagination and some have no representation of my personal life, but 'Lonely Lullaby' was the first song I wrote almost entirely about something as personal as a romantic relationship... The song is, in fact, so personal, it almost hurts to listen to it now that such a perfect relationship has come to an end. I wasn't sure if I had something as 'genuine and pure' inside of me but the song basically wrote itself and I'm proud of it."

Composition
"Lonely Lullaby" is a melancholy-influenced piano ballad written and produced by Adam Young of Owl City.
