Great article. It's wonderful to see rhythm celebrated for how it makes us feel.
The Guardian had an article a few days ago on an emerging emphasis of bridge rather than chorus, and the role of repetition, in recent blockbuster hits by Ariana Grande, Iggy Azalia, Nicki Minaj and others.
The article has a great quote from the founder of Motown:
"Don’t bore us, get to the chorus!” Berry Gordy once joked, understanding that this is what listeners truly gather around.
