I think the reality is lots of pins could be made that people might not know they'd like until they tried them. If you just ask for music people say they want you're gonna hear the same rock bands you always hear, just like you see the same 80s movies in every dream theme thread. That doesn't mean that's the only market or the only thing that would sell. Music is always personal. Plenty of people don't like Iron Maiden or GNR, doesn't mean they were bad choices either.
If you started a poll asking people if they wanted an EDM pin it would likely get a lukewarm response, but if there are people who don't love how TNA sounds I haven't met them yet.
High energy music is good pinball music. Yeah, pinball is full of old white men, but the truth is the demographic that's becoming bigger in the hobby, and who has money, are young enough to have grown up with rap. Maybe a more "urban" sound wouldn't sell to the people in their 60s, but people in their 40s might be a different case. There was a time the older generation was shocked by bands like ACDC too, and thought it was crap.
But in my mind at least it's less about the audience and more about the creators. You need people who are passionate about a theme to make it work. And I dunno who that would be. Hard to see it coming out of Stern for instance.
