Query: Pleasant, But....

I have read most of the material out there from musical studies and analysis to books intended for general reading by the public on the subject of Haydn, Mozart & Christian Bach. The reason being, to try and get an overview on the subject from different perspectives and cross analysis. This book does not offer much new information in that regard on the historical background leading up to the Classical Period, either politically or musically.However....To say that "most" of Mozart's music is missing something compared to Bach's (is it 51% or 99% that is involved in this statement) is quite daring. What would have been even more daring is telling us exactly what Mozart was missing in his music. Maybe our learned author will tell us in his next book.
