Go check out "Grime" hiphop. That's a hiphop movement that I think should get more traction here (especially over crap like Reggaeton).
UK is pushing the hiphop envelope right now (With artists like Roots Manuva and producers like Coldcut, DJ Vadim, and the rest of the ninjatune label), but there's some really good continental acts like Rhajha and Saian Supa Crew.
Check out The Herd from Australia too.
