Wow it's the first time that I don't know part of what i'm talking about and i'm still right...

MySpace is mostly erased (prominent Italian musicians for some music waves of the 00s and 10s were there), some sites are erased, what pertains to radio and television is mostly not indexed on the public internet and there's significant digital divide between genres. In the Italian context, you'd end with a weird pantheon of rock, rap and popstars and not much else left, in conclusion you would... expunge significant artists and whole genres from results.
