Larry Flick from Billboard wrote, "Taken from her new best-of collection, "Paint The Sky with Stars", Enya delivers yet another great single. "Only If" is as peaceful and memorably melodic as any other of her inspirational, soul-purifying songs, which traditionally are etched with a unique combination of background voices with drums and violin lines. It's a combination that makes all her songs seem antique, almost, if not angelic. Enya can many times take her listeners into another dimension altogether, and this single is a fine example of that."[1]
