《Vocal Class》是刘若英的一首经典歌曲，歌词通过反复的问答形式，探讨了人们对“酷”的定义以及自我认知的矛盾。歌曲以一种诙谐而深刻的方式，揭示了现代社会中人们常常陷入的一种自我矛盾和虚伪状态。
歌词中不断重复“You think that you are cool”，体现出一种自我欺骗的循环状态。这种循环式的表达，象征着人们在外界标准和自我认知之间摇摆不定。而最后的“Well you're not cool”则是对这种虚伪的自我认知的一种否定，揭示了人们在追求“酷”的过程中，常常忽视了真实的自我。
You think that you are cool You think that you are cool You think that you are cool You think that you are cool You think that you are cool You think that you are cool You think that you are cool You think well you're not cool Well you're not cool You're not cool You're not cool You're not cool at all You're not cool at all
