Songs are (in general) not "musicized" poetry. It's closer to a movie. People work on it and it sells as a whole. Lyrics + music + singing or screenplay + scene + acting (simplified). I don't see why I should pay anyone for quoting a movie. Nor I don't thing lyrics of a song are worth anything as standalone. Those who wrote the screenplay/lyrics have deal with owner of the final product and are paid from that (or were paid once and that is one extra reason to not pay them over and over).
