Q: what are the chords in hello sexy panys leading to "down in congress"/"then go to Pyongyang" parts and in them, and can you explain why it hits like that?
A: nothing leads into them, but during those parts it uses B over Db. (coming from the previously established key of Ab major of course). My best explanation for why it hits like that is because people don't do this that often anymore. it's a fairly normal thing to do but it just hasn't been used that much lately, so that might be why it sounds fresh. it might have been used more in the 70s maybe, i'm not sure
