what does Iggy more hip-hopish than Drake or Nicki?

Is TNC more hip hop than Pink Friday: Roman Reloaded?
Yes.
Is most of TNC more hip hop than songs like: The Night is Still Young, Grand Piano, etc?
Yes.
Does Drake sing more than Iggy?
Yes.
Does Iggy use hip hop and electro-hop beats exclusively?
Yes.

The only difference is quality (which is subjective) and that Iggy is white.

Of course everyone is saying she didn't when in fact she's helping to open the doors for white female rappers.
