I've wondered this for a while aswell...
Fair enough I understand producers an people saying suport the scene when the tune will be released... But I aint gonna feel guilty for having a unreleased tune i.e. A Bit Patchy (Sub Focus Remix), Triple X etc.. and all the sick VIP's that dont get released as the producer isnt losing out if he aint gonna release it anyway... Also if I get a good dub, I will always purchase the vinyl when it comes out anyway as I prefer mixing with vinyls... An I wouldnt do a set on cdj's so the tune is normally for mine and only mine listening pleasure... If I was a big producer and I knew I was never going to legally be able to release a tune i.e. something like Sub Focus - World Of Hurt which is an absolute anthem if you ask me then I would bootleg it an say fuck you to the owners of the sample or just give it away in mp3 format, whats the point in created a big tune like that if no one is going to be able to enjoy it, I mean the tunes stopped getting played all ready, so in a year or so I dont think you will ever hear it again... So I agree with tunes like these getting leaked. Fair enough it is someones work but what did he create the tune for? To be heard...
