The world champion here would have to be The Beastie Boys “Sabotage”. It’s arguably the best song of the ‘90s, and the lyrics are improvised nonsense that nonetheless sound awesome when shouted.
It’s possible that there’s something meaningful to be extracted from Beck’s “Loser”, “Devil’s Haircut”, “New Pollution”, and so on, but after decades of trying, I’m convinced they just sound great and mean nothing.
Of course, the Intentionally Stupid Just To Fuck With People special award of merit goes to Lennon-McCartney for “I Am The Walrus”.
