Did you ask him if maybe the problem is that he's always been mediocre himself? I mean that quite seriously. The comment about how he'd write "big" tracks that would get "played for months" is kind of what hinted to that for me. The tracks that I, and others, considered huge from the days of past are still ones that manage to make it into my DJ sets when I do it, and are regular plays in my car or home, now well after a decade from being released.
