One thing I'm super aware of in my music when I'm writing is: 'Am I overcomplicating this?' I'll write a song about some deep existential quandary and explore all these dumb thought waves, and then think 'Is it effective to say that? Or is it effective to say one simple thing that communicates the feeling better?'
In detective land, you have to deal with a lot of intense emotions, so you yourself have to remain mostly unemotional and detached. These are people, like law enforcement and surgeons, in professions that don't have the luxury of being able to be emotional or to break down. In my line of work, it's almost a requirement.
