Accidentally stumbled across what I'm pretty sure is the inspiration for The Curse of the Sad Mummy

Not sure if this was known by anyone or of it is acknowledged by Riot anywhere, but I was listening to some random youtube playlist when I heard this song start playing:

(It's kind of long, just play it in the background while doing something else, that's what I was doing)

About a minute in, I did a double take and checked to see if I was listening to a cover of The Curse of the Sad Mummy. Then I saw the title was "The Curse", realized all of the lyrics were different, and came to conclusion that Riot probably took inspiration from this song for their own Amumu song (this one):

Maybe I was hallucinating or something, because the more I compare them the less similar they sound, but at least if you like the Amumu song you may like this song because they have a similar theme I guess.
