"[4] The following year, in December 2010, Li told The Guardian: "I was sitting in a car in England [when I got the call] eating a sandwich from Tesco, and I had no idea what Twilight was.

'Tell me when you hear my heart stop,' she sings, while a backing choir inflects the sparse piano with gospel undertones—a brief, largely a cappella prayer.

"[7] Consequence of Sound critic Anthony Balderrama noted that Li "channels some of the more intimate moments of her short career on 'Possibility'.

"[8] IndieLondon rated the song four out of five, stating it is "as beautiful and haunting as we've come to expect from this Swedish performer... and perfectly ethereal to accompany staring out the window at a snowy landscape.

"[9] Marc Hogan of Pitchfork commented that the "feedback-streaked piano ballad 'Possibility' is a relative bright spot, but like the rest of the tracks [on the soundtrack], it pales in comparison to the work on her own records.

"[10] Krista Richmond of KillerFilm called the song "lovely in its haunted, enchanting way" and added that it is "soft and melodic enough to pull at even the toughest of heartstrings".

[11] MusicRadar's Joe Bosso opined that "[t]his stark, piano-based hymn is spiritual stuff, and Li's arresting vocal powers will have you on your knees in worship.

[15] The music video for "Possibility" consists of Li's live performance of the song at Stockholm's Decibel Studios on 9 March 2010, and was directed by Marcus Palmqvist and Frode Fjerdingstad.
