But generally, irony as a way of appreciating music isn't about saying "ha ha lets make some shit music, won't that be funny." Even for the most coke-addled hipster, that's got to get boring after about twenty seconds. It's more a way of listening to music that you enjoy but that you can't admit - to your friends or to yourself - to liking. Irony is the safety net that lets you genuinely get off on music that is in one way or another uncool. Obviously the fact that certain kids can't admit to liking grime in an honest fashion but go mad for it when it's presented in a repackaged fashion is nasty itself. Although you might hope that since Hadouken don't exactly try to hide their appreciation of grime some of that might rub off...
As to Hadouken themselves, you can think they're shit but a) given the amount of complaining around here about indie guitar bands being only influenced by indie guitar bands and not taking on any of the varied and exciting ideas thrown up by dance music, it seems a bit harsh to slate them just because they try to take influence from grime and b) if you've read any of what Dr Venom writes it's pretty obvious that he's a serious and genuine grime fan and not just doing it for the irony.
