Meaning of "Sane" by Buck-Tick

The lyrics of "Sane" delve into the complex emotions of embracing one's madness and finding a sense of liberation within it. The repeated phrase "Now I'm insane, but I must go when I go" suggests a recognition of mental instability but an acceptance of it as a necessary part of existence. The juxtaposition of insanity with expressions of freedom through dancing, singing, and the sensation of flying, illustrates a duality in the human experience. The protagonist seeks something to believe in and finds solace in the burning passion that propels them forward. The repetition of the line "Now I'm sane" at the end of the song could be interpreted as a paradoxical statement, suggesting that true sanity lies in accepting one's madness and living authentically.
