power ballad complete with
gospel choir and tribal drums."
Larry Flick from
Billboard magazine described it as a "stately power ballad" and an "outstanding recording". He remarked that Estefan "has rarely sounded so vocally flexible and confident, broadening her range to wonderfully appealing heights within a softly building pool of percussion and gospel-spiked choir chants." He also felt that "by the dramatic close, the song has risen to inspirational anthemic proportions."
Billboard editor Paul Verna declared it as "uplifting". The Daily Vault's Mark Millan named it the best track on the album and added that 'musically it's very "international" and lyrically it's very uplifting.' Chris Hicks from
