World Calling is a beautiful song that's not only about showing off the massive talent of the animator as a means of expressing the many, many creative ideas they have that can be seen in the visuals of this video, but also the lyrics and message, which is one that's inspirational, hopeful, optimistic, and other words of the kind. It's really something delightful and charismatic, and although it lacks a conventional story, that's not the point of this song; it's simply meant to convey happiness and adventure from the perspective of a fairly young girl, and it achieves just that. Accompany that with the stellarvisuals, which are used to the fullest potential, as well as the great music itself, this song really works as a whole, and I very much recommend spending just 3 minutes of your life to watch this.
