Bed of Thorns

This song by Gary Numan is called instrumental by some people when it is not true. It has lyrics, and there are plenty of them, enough for several couplets. He is the English composer, singer, and a songwriter that performs in many genres: new wave, synthpop, post-punk, electronic, industrial rock, gothic rock. This piece is rather a fusion of post-punk synthpop, in line with the general idea of the film itself made in the post-punk sci-fi. It is sung about the emptiness in the soul of a performer & that he is hiding from the entire world. He feels that everything is the dust & he walks through it.
