Andy Grammer's new song was originally a lullaby he sang to his baby daughter.

The 33-year-old singer-songwriter has revealed his new track 'Always' - taken from his new album 'The Good Parts' - holds a special place in his heart because he played it to his now-three-month-old daughter Louisiana to get her to sleep.

Speaking to Billboard, he said: ''I was singing that to my daughter right when she was born, and she was still kind of crying. I'd put her in a little cart and do a lap singing that song to her. It's very sweet and emotionally connected to me... I've been bumping it in the car - me and my little three-month-old, we go to coffee dates every morning and I play that song to her, it's so sweet.''

And that wasn't the only song on the album that he played to little Louisiana as he has admitted 'Spaceships' was one he sang to her while she was in the womb.

He explained: ''That's like, the best bridge I've ever written, which is comparing to the womb - which is the world before this world - and wherever you go when you die as the place after. As I was singing into the womb to try and let Louie know that she was coming to someone that loves her, I imagined, while I was singing to her, 'Ah, I wonder whether my mom is doing that to me from wherever she's at?' She passed away. But that's such a cool idea.''

'The Good Parts', which was released last week, features some of Andy's most personal songs - including 'Smoke Clears', which documented his health scare.

He said: ''It's very autobiographical, about a health scare that happened when we were on vacation in Ireland. I fainted in the shower and chipped my tooth and looked like I was having a seizure because I hadn't slept in like, two years.''
