copyright issues. According to Douban.com, major audio apps lost the copyright of Thin Love Song at the same time, which led to the removal of Thin Love Song. Thin Love Song is a popular non-love song written by Huang Weiwen and sung by CAllStar. This song uses metaphor to discuss the relationship between fans and the music world from the point of view of the lyricist. It compares "I" to Cantonese pop music and "you" to the current audience, but "I" can't please "you" and "Cantonese songs" can't cater to "the audience", describing the cruel reality that Cantonese music world is gradually declining.
