Dubstep is not meant for what you call a "Bassdrop". Dubstep is an electro-styled music/dance that has Bass lines running through it. With modern dubstep we brung Dubstep to the point of there has to be a "Bassdrop". But that is not true, let me refer you to http://en.wikipedia.org/wiki/Dubstep Thank you.
well... i would not call it a dubstep song... that's a blend of house and dubstep... with house prevalence...
i didn't hear any bassdrop... well.. theres is the one in 0:58... but it's still boring since the dubstep part is just in the background...
but... since i'm not able to do these kind of songs, i don't even know how hard is this... so i'm not able to understan how much you worked on it... i'll just base my rating on my experience on the listening of some skrillex's songs...
my rating is: 5/10...
just because it sounds more house than dubstep =/
