[Barry the Sprout]

I don't think anything beats pretty much the whole of OK Computer by Radiohead. Sections of which are:

Would you please stop the noise I'm trying to get some rest,
From all the unborn chicken voices in my head,
What's that? WHAT'S THAT??!!

Later on it has:

Karma Police, arrest this man,
He talks in maths, he buzzes like a fridge,
He's like a detuned radio oh,

Or possibly "Life in a Glasshouse" on Amnesiac:

Once again, we are hungry for a lynching,
Packed like frozen food and battery heads,
Don't talk politics and don't throw stones,
But I repeat myself,
Well of course I'd like to stick around and chat,
Well of course I'd like to stay and chew the fat,

Radiohead truly are the band for weird indecipherable lyrics.
