I just found a song that came out 5 years earlier than Call of Ktulu but with same riff

I roam around ultimate guitar pretty often, but never bother to create account and post until i heard this song on radio and was confused when i realised its neither Metallica nor Megadeth and wanted to share this with all of you. So check it out.

Compare this
 Srebrna Krila - Sanjar Lutalica 1979

to this
 Metallica - The Call of Ktulu 1984
or this
 Megadeth - When 2001

Both this riffs were written by Dave Mustaine and sound identical to Sanjar Lutalica

I am not saying that Metallica/Dave stole it becouse they/he proved through all those years that he can write awesome riffs, it could be just coincidence but i wanted to share it with you and hear your opinion

Proof https://hu.wikipedia.org/wiki/Srebrna_krila_(album)
Of course its a coincidence, i doubt Dave heard and lifted a riff from an obscure yugoslavian pop rock band from the 70's. But this thread did make me smile, since i come from one of the ex yugoslavian countries.

I guess we have this band to thank for kall of ktulu:
Joža je kul. On ma sirove z dodatki pa hambije.
That's a pretty common progression.
