You were able to sing something they related to instantly, because it was part of what you felt. It was part of what you had already traveled through. It's part of the people you were associating with daily. It was all of that.
There are some good songs, but not the kind of song-writing that I remember, that I like. Springsteen still does it. Paul Simon, and there are also good writers, but that doesn't dominate the charts.
