Begin Again marked Knightley's first singing role. Although she had never sung professionally before, she trained with a vocal coach to prepare for her role and also learnt to play a guitar.[7][8] Speaking to Daily Mirror, Knightley said "I don’t listen to a lot of music and one of the reasons I wanted to do the film was because it was a challenge and something completely different for me. The whole thing was out of my comfort zone... I’m not a singer and I didn’t know how to do it."[8] She had also contributed vocals for most of her songs in the soundtrack.[9]
‘Lost Stars,’ more than any other song in the film, was the one where you wanted to get out a philosophy that Keira’s character would sing but Adam would relate to and something that would also touch a contemporary audience. At the end of the film, it’s a young audience watching this song that really has a lot of pathos and pain in it, but yet people are doing this
Being a fan of Carney's work, Alexander sent some of his compositions to Carney through email and MP3 until they officially met in London and discussed about the music. The script undergone multiple re-writes as the original songs had to be altered in order to seamlessly woven into the narrative.[10] Alexander said it as "The way that the songs began didn’t seem like there was a count off –one, two, three, four– there was no false sense of expectation because there was a big build up. It was like a car that just got started up and the next thing you know it’s driving down the street at one hundred miles per hour."[10]
Alexander was initially intended to write the original song, but instead after reading the screenplay, he felt so compelling, which resulted him to contribute to a body of work instead of an original song.[11][12] While writing the track "Lost Stars" with Danielle Brisebois he felt that, "I was under the impression — or illusion — that the spirit of the characters were in me, hopefully to the point where I could write something they could sing without self-editing".[12] His collaboration with other fellow songwriters, Nick Lashley and Nick Southwood helped him to complete the recordings of the soundtrack by 50 days, even before the film's shooting was set to begin in July 2012.[12]
Track listing
Begin Again (Music from and Inspired by the Original Motion Picture)
Writing for Renowned for Sound, Helena Ho called it as "a great soundtrack that depicts the mood and premise of the film completely. Most of the songs on the album are easy listening, chiller tracks. The input of Cessyl Orchestra is a welcome change, as they bring a fuse of alternative rock with their electric guitar solos and dreamy harmonies. The soundtrack shows variety without straying too far from the heart of the films’ message. Each song is performed with soul, proving that music isn’t just about feeding a market; but really, it’s an art form that can truly express one’s emotions."[13]Mint's Sanjukta Sharma called Alexander's music as "intoxicating Mitchellian graft".[14]Mark Kermode of The Guardian, felt that "the songs are serviceable, if not spine-tingling".[15]
Writing for Rappler, Paul John Caña said "Music is such an integral part of Carney's oeuvre that it’s almost like its own character [...] Alexander composed many of the songs in the film, which should appeal to fans of acoustic guitar-driven music. The songs chuck the toothache-inducing, saccharine sweetness of bubblegum pop in favor of raw, honest, hey-that’s-me-they’re-singing-about reality. This is exactly what a film like Begin Again needs, and in this respect, it’s already a winner. There is a feeling of discovering a new artist, and being treated to awesome new music, and for any true music fan, that’s one of the best feelings in the world."[16]
Richard Lawson of Vanity Fair wrote "The music, central as it is to the story, could have sunk the film had it had perhaps even the slightest whiff of contrivance or inauthenticity to it. Excitingly, most of it doesn’t. The songs, written by New Radicals front man Gregg Alexander, with contributions from collaborators including Once star Glen Hansard and frequent Lykke Li and Lana del Rey songwriter Rick Nowels, are vaguely folky pop tunes that work credibly within the context of the film. And outside of it, too; I’ve found myself listening to one or two of the songs on YouTube since I saw the film. Certainly not as many times as I’ve listened to the beautiful “Falling Slowly” from Once, but it’s still an admirable achievement that the songs from Begin Again stand on their own as well as they do."[17] In contrast, Ann Hornaday of The Washington Post criticised the music as "twee, wispy and instantly forgettable",[18] while The Oregonian's called it as "pleasant, but nothing special".[19]
