I see a similarity in the chorus but it's no where near a copy. The notes aren't even the same. You want to see some copying check out "Watch the Throne". Blatant theft there.
I don't think they sound anything alike except for: 1) they're both chanting during the "chorus" 2) they're both equally AWFUL
I tried to determine, but after 5 seconds of listening to each one, my ears started bleeding and I had to stop.
