cudi is going in the dance direction, some are pop-ish like kanye and drake. (or lupe ) that's the style to go ...drake made it from zero to "top" in about 1 year.
...because, if a rapper isn't able to make it overseas, no way he will be considered to run hip hop.
people here don't know about currency, wiz, lloyd...
If they are not even popular now they are not going to be running shit
...so who knows.
