Dude you gotta realise that in comparison to other genres, DnB is poorly funded. Also a good percentage of us on here would like to make a living of the music we love one day so when you come on here asking for free (which usually means illegal) MP3s it pisses a lot of people off. Also dont be too offended cos anyone that comes on here asking what you did (which happens a lot) they get the same treatment.
So if you love the music you should support it. Like Riisu said try places like beatport - you can get quality tunes for like 80p on there.
