I recall back when that song came out, and in the back of a Guitar Magazine they tabbed it out with lyrics and it said something along the lines of “you have something I want and I take it from you.” When I listen I cant hear anything but that.
Well. I never wondered until now. If there is an acapella of the main vocal then it would be easy enough to remove that from the backing. If that isn't available somewhere then making it mono might help with intelligibility - as it seems to be autopanned. Not sure, might simply be double tracked.
I'm intrigued. Usually, when I hear something, I can at least come up with some nonsense. I'm getting "pick up a" somewhere in there but can't be sure.
I'll see how much I can isolate it and have another go later.
This doesn't help directly but it's the closest I could find to an acapella without searching deeply:
