I'm sure he does have something to say. But if he doesn't feel the need to express it lyrically, all the more power to him, I guess. Billy has always struck me as someone who says things like he sees them. And in this day and age, that's difficult to do, unfortunately. I mean, who wants a 70-year-old pop rock star complaining or calling things out? He'd just get hammered on, ya know? And even if he just kept it relationship-based, what's he going to talk about - how much he loves being a rich old guy with grandkids?
So in some ways, I understand his silence. He can rock out to his old standards, where everyone in attendance is happy, and not have to think about writing new material that people can relate to.
Although I'll obviously never be as rich or famous as Billy Joel, I understand to a degree. Things I think about and say now, from my perspective, are that of a middle aged white dude from New York. The world is a lot more diverse and colorful than it was while I was growing up. So different. My "perspective" is outdated to a degree. (As much as I can't believe how much time has passed.) And if I were a songwriter, I'm not sure I could relate to folks a generation or two younger than me. And Billy would need to.
