From Top 40's to Dubstep

Is anybody else noticing the changes in top 40's music? The 'Top Charts' artists are starting to conform to the dubstep genre while keeping the pop feel in their music. I've only heard a couple songs that have actually been able to pull off the adaptation and it actually sounding good & these are Too Close by Alex Clare & Sorry for party rocking by LMFAO. Pitbull tried doing it in his new song Around the World & in my opinion its terrible. Every time it comes on the radio i rant & rave about the fact that the dubstep part in the song doesn't go with the rest of it at all. But that's just my opinion. Its not just dubstep that's been infused in Top 40's music, LMFAO's Party Rock Anthem has Dutch house in its main "chorus" if you will, & so does Rihanna's Where Have You Been which are both great songs. So i have a feeling that I a couple years Dubstep, House, & other electronic music genres will rise to be top 40's music, Specially with Skrillex, Datsik, Excision & others artists blowing minds all over the world.
