Definitions of an EP all came from the vinyl era. Three songs would make a maxi Single, from 4 tracks on it was indeed called an EP. The term "EP" alone shows that MK thinks more in terms of the vinyl releases of his younger years. He mentioned those old EP's he still has on his mantlepiece. Of course in digital times the EP lost its relevance. The What it is Single would have been a real EP if it had been released on vinyl and on it's own. In 2000, those 4 tracks were just a "single".
