The first single from Tong Yu's new album has obvious work put into the production and choregraphy, but I like the slightly naive sound for what it is with the nerd/looser theme of the video matching that well.
This is one of the hits of Quest Pistols that I've missed. The cooperation with "Lolita" (who in no ways is a lolita in its original sense, and weight is part of the lyrics' theme) is great and even if it is kind of "nicer" than many of their other songs it is basically the same.
