If I Only Had a Heart
"If I Only Had a Heart" was a song from "an old Earth movie", The Wizard of Oz.

In 2365, Ira Graves whistled the song when he met Data. As Data did not understand, Graves explained how the song was an allegory for Data's own predicament: a mechanical man wants a heart, but learns that he is Human and had one all along. ()
