The power of copyright-free song titles

To underline the point that song titles are, by and large, uncopyrightable, here are four melodically unrelated songs all called ‘The Power of Love”. Writing one seems to have been compulsory during the early 1980s:

Jennifer Rush
The Power of Love (1985)
(Celine Dion covered this version in 1993)

Huey Lewis and the News
The Power of Love (1985)

Frankie Goes to Hollywood
The Power of Love (1984)

Luther Vandross
The Power of Love (1981)
