I like this song very much. I thought it was just a pure music version, so I tried to listen to every syllable carefully. I feel that this song expresses the author's desire to pursue one of his dreams, but he has tried many times without results. Every electronic sound that the glee club wants to explode ends with a drum. Although he failed many times, the author still didn't give up and was still ambitious. Later, I heard a version with lyrics, which was really similar to what I guessed. This song is really inspirational, so it also resonates with many people all over the world!
