So has linkin park complained?
I doubt whether they will complain

Furthermore Emmy Kosgei took Vuli Ndlela and made Taunet Nelel out of it, and won internationa awards. Nowadays, what matters is the message u r putting across. Very few are in the industry to prove how creative and original they are. We have seen many original ones with no message to pass across. In my view, that song is laden with a very strong message.
