How about Phil Collin's "Susudio". Phil occasionally used nonsense words as placeholders while working out the melody.

Obviously, this song was the rare exception where the placeholder wasn't removed.

While lyrically some of his songs may be stream of consciousness and contradictory, that didn't stop them from being huge hits.

The approach of focusing on the groove first and the lyrics last served Phil well. A song doesn't make much sense, as long as it's catchy and triggers an emotional response in the listener.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
