Full Disclosure: I listen to non-jewish music!!
That being said, I do not know if the singers themselves know that it is copied (i have a feeling yes, but i will be dan lekaf zechus).
However, jewish music, in the past, has copied from: AC/DC, Scorpions (Lev Tahor Asher Bara and Rock you like a Hurricane), Andrew Lloyd Webber (Joseph/MBD), Rihanna and Lipa Shmeltzer, U2 and Shalsheles (the bridge of “Sunday Bloody Sunday” and Kel Hakovod sound very similar, do they not?), Lev Tahor and one of the artists from the “Shrek” soundtrack (the L.T song is: Avinu)
I could go on … would anyone like me to?
