The two I always notice are "Bitch," in which Mick Jagger sings that his heart is beating louder than "a big bass drum," pronouncing bass as if he meant the fish rather than the deep musical tone, and "Jet," in which Paul McCartney thought the major was a lady suffragette, pronouncing the last syllable with great emphasis and with a hard g. (I presume the mispronunciation is by way of establishing emphatic contrast with the j sound of Jet at the beginning of the line and is therefore deliberate. I mean, the man's a knight of the British Empire. He has to be able to speak proper English, doesn't he?)
What such transgressions do your favorite songs commit in the name of poetic, melodic, or lyrical license?
