This might be a different kind of route you'll want, but if you want to read from the source, look up "Songwriters On Songwriting: Revised And Expanded" which has personal in-depth interviews, including a variety of pop history stars.

Also if you want to check out mostly quite recent popular songs, and some highlights of the tracks with commentary, see Rick Beato's What Makes this Song Great playlist. https://www.youtube.com/watch?v=ScRG40_7zb0&list=PLW0NGgv1qn...
