"[5] Chad Grischow for IGN described the song's piano led instrumental to be "overblown", but noted that Lewis has enough "vocal strength to prevent her from being overshadowed by the drowningly lush sound.

"[3] Eric R. Danton wrote on his review of Spirit for the Hartford Courant daily that "I Will Be" begins with a "spare piano introduction" that "blossoms into an arrangement buoyed by strings and then drums and guitar".

[8] Matt O'Leary for Virgin Media wrote that Lewis's rendition of the song was "epic", and that when the production is kept minimal, "her uniqueness is allowed to shine.

"[9] Although Sarah Rodman for The Boston Globe described the song as "predictable", she praised Lewis's ability to sing with "believable pathos" and hit clean notes.

"[7] Upon the release of Spirit in the United Kingdom, "I Will Be" debuted and peaked at number 160 on the UK Singles Chart from digital download sales.

[26] The music video for "I Will Be" was shot in New York City on 18 December 2008, and features Gossip Girl actor Chace Crawford as one of the characters.

[27] A reporter for People explained how the inclusion of Crawford in the video came to fruition, writing that "Chace went to London a couple months ago for meetings and to promote Gossip Girl.
