I noticed some famous artists use certain words or phases as "catch phases" to hook people. I wondered why that works so well.
Communication of an emotion or expression that paints a picture or story takes some thought & ability to reach people. I heard a critic use the word "relevent" recently....meaning the artist communicated to some recent theme or popular thoughts. Sounds a little over critical of the material to me, but I'm not trying to make a hit recording.
