Jenny Lewis might be doing her solo thing these days, but that doesn't mean she's stopped working on projects with other artists. Case in point: Recently she collaborated with Johnathan Rice to pen songs for Anne Hathaway's upcoming film, 'Song One' -- and now we get to hear one of the fruits of their labor, 'In April.'

Sung by actor and musician Johnny Flynn -- who stars opposite the Academy Award-winning actress -- the song's lyrics go through the ups and downs of love and floats on a sweet and simple acoustic melody. 'In April' is one of the tracks that leads Hathaway to Flynn's character as she tries to find the people who surrounded her comatose brother surrounded. The two characters end up falling in love in this heart-swelling romantic film.

"So why did you fly away / I've been dying a little death since that very day / I used to lie when you told me / You must forget to forgive, to be free," Flynn sings in the chorus.

Lewis and her partner wrote more songs for the soundtrack, but they don't actually sing them. However, while reworking the script for the film, director Kate Barker-Froyland found inspiration in Lewis and Rice's music.

"While I was rewriting the script in New York, Jenny and Johnathan were creating these amazing songs in L.A.," the director told Rolling Stone. "I only had placeholders for the songs in the script, and as Jenny and Johnathan sent me demos it made James' character begin to come to life."

'Song One' hits theaters on Jan. 23.
