A couple of these are inaccurate:

Bon Iver and NIN are both bands with more than one member

The BeeGees formed in Australia but they aren't Australian, same with AC/DC who are (mostly) Scottish

This is wrong on so many levels:

Elvis and Tupac were often referred to by their full names

Atticus Ross is now in NIN, Justin Vernon has various people working with him in Bon Iver (certainly since the first album), Kevin Parker doesn't tour alone

And the Oz thing has already been pointed out.

Good effort but pls d yr hmwrk
