This music can be considered a song unless with a strong stretch. Yes, there is a chorus of voices that enhances some aspects of musical sound, but they are almost merged with the melody and not discernible, even unclear whether voices belong to men or women. This is great music often used to emphasize the strength or the terrible majesty of the moment. For example, in 10 sec before an imminent collision with a huge asteroid. Or when a giant dam breaks, going onto a million city.
