SGotI named Franklin Benedict is going around tracing the downfall of the Costearndoza Mets to the day Brian Wilson died.
I'm not one to endorse the idea of curses, as there are certainly enough reasons that things go to shit as observed through the lens of rationality. But if there is such a thing, I tend to agree that this is enough of an insult to the universe to bring a curse about.
That said, in my brief search for accounts of that day, I was only able to find one or two accounts of "I Get Around" being featured over the Citi Field PA. So maybe this guy is full of it, and the Mets failures' are due only to sensible, baseball reasons, like not signing any utility infielders with hit records.
