The best songs never use idioms. Our band tonight has moved into a song that may be an original that has the chorus “the harder they come, the harder they fall”. This is right after they played all along the watch tower and the scientist. Neither of these songs relied on idioms. Idioms have no place in music. They can barely justify their place in the world when people should think and elaborate rather than relyiing on tired old ways of saying old truths. They have moved on now to “no woman no cry”. It is a huge improvement over the idiotic idiom song.
