I think "Mass" is very familiar, because it is adapted from "Rouge Flower Rana" (a poem by Bran). It is said that "the military song of the First Armored Division of the German Armed SS was also adapted here during World War II", which led to a similar tune. Zhang Guan Dai Li believed that Mass was a Nazi military song.
Now, with the increasing popularity of this song, more and more games have absorbed its energetic and inspiring side. Among them, World of Warcraft, the most popular online game, uses THEMass as background music in a large number of homemade game videos.
