I think that UK grime will overtake US hip hop music if hip-hop keeps going down hill. any thoughts?

appart from 50 n kanye's new albums i havnt heard a good rap song all year come out of the US all these new MC's like mims and young joc should go back to their day jobs. on the other had UK grime is improving alot and although i wasnt a fan straight away it has grown on me. well thats my opinion anyway
