you talk a lot about picking chords to support the melody, but what are your thoughts about songs which go for a significantly more complicated and frenetic chord structure than the vast majority of composers would likely pick for that vocal melody, such as in this song https://www.youtube.com/watch?v=gtExkfaeAzQ ? is this something you ever envision yourself trying out in your tracks-longer-than-30-seconds songwriting?
there are many many ways to support the melody, including ways that are much more complicated than 'most' composers might use. i have used many, the song you linked uses many, and there are still many many more.
