I used to like in when i was an early teenager but i grew out of it i like some but only the old ones from people like Kano and Dizzee Rascal and Devlin and a few others but i don't care about the "scene" it's basically full of chavs that make "music" for other chavs and what makes it worse is when grown men act like these little chav teenagers it's so cringe worthy..
I actually prefer American Rap/Hip Hop nowadays though but just like both genre of music they both have gone down hill it's more about the beats than lyrics
The oldschool stuff is probs a better example to show than what you chose. The reason why Grime is going global at them moment is purely for the instrumentals. Barely anyone outside of UK understands what they're saying. I've loved Grime since a kid and it brings me back to the UK
