A subtype of excellence is a song, which work with just a few (couple) of the instruments. And in this category you’ve got for example Get on the Floor – a stunning track even when stripped down to just the drums and bass! And as we all know, the drums + bass (rhythm section) formula is a re-occuring one in Michael’s discography.
Then you have songs like They Don’t Care About Us, that’ll work with just the percussion. Or She’s Out of My Life – beautiful with just the Rhodes.
As for your original question: Wouldn’t it be easier to come up with songs that absolutely do not work without vocals? (Just spitballing here. As for me, I don’t—at the moment—have any songs to suggest here either.)
