An unenlightened person may say, “duh…that song is actually called ‘Brandy You’re a Fine Girl!’ What kind of fool doesn’t know that? Ha ha ha!”
But NOOOO! There actually is a song with the one-word title “Brandy.” And for a bonus song that fits the OP’s rule, “Brandy” was remade by Barry Manilow, but he changed the name to “Mandy” in order to avoid confusion with “Brandy You’re a Fine Girl”!
