What I recall from decades ago… those that weren’t really into music were into Springsteen — overplayed frat house noise
Clearly, you were there.
I don't know about the frat houses but most of the Bruce Springsteen fans I ran into were pasty white guys who weren't into music at all. A lot of jocks and a few of their wannabes, neither of which could tell you the first thing about any other music.
