Personally, I think it is a conceptual song. Classical music is often used as part of therapy. Jon probably used this type of music during his therapies conducted by Lou Cox. For the workshop Jon took the subject PTSD (post-traumatic stress) so ... A song on this subject ideally fits a melody similar to a classic composition. People who hit this trailer will catch it immediately and they won't even know why. It also evokes positive emotions. This is one of the pieces targeted at a specific audience.

From our perspective, the use of such a melody can be cynical etc., but I can imagine that it will be for Jon one of the most important songs in his career because of the personal emotional charge that it carries.

There is nothing to tell about the fact that many hits use themes from classical music, because it is obvious as well as the existence of 4 chord songs.
