SOLVED Rock song from the 90s in the chorus he sings "hun-nun-na nun-nun-na!"
Or something like that. I can't find it because obviously those noises are not proper lyrics (and I don't remember any other lyrics) so can't do an internet lyrics search!
I believe it's from 90s because I heard it (couple of times) on a 90s radio station, could be 00s though.
