Yes, I'm aware. Although a major mega band doing so on a wide release album these days would be taking a significant legal risk - which is why it's now fairly rare. But back in 1979 it wasn't uncommon, to the extent that one of the then-biggest bands in the world could do so on their biggest album project yet.
It might be a notorious example but artists do take those risks https://www.billboard.com/lists/kanye-west-ye-sampling-lawsu... (not to mention the many artists that release music without licensing from the beat producers, which still happens regularly)
“Grant Upright Music vs. Warner Bros” almost completely killed any creative use of sampling on official releases, which is why the only place you still see it consistently is mixtapes. Think 50 Cent’s “The Undertaker”.
