i didn't spin a few years ago but i was producing.
o.k. the scene was different then , we were all selling records for one.
its a bit of a witch-hunt this question really.
i mean no one goes into the studio saying to themselves :

"aha this'll fool the stupid bastards into buying my records!!!!!"
(rubbing hands with glee)
"and i don't even buy anybody elses records hahahahahaha!!!!"
(like a james bond supervillan)

i think i can speak for most of us and say that we all make our music because we love it , and that's about it.
one way or another whether it becomes your job and a neccessity or whether its a hobby this is underground music and most people get into it 'cos they really enjoy listening to it
even the most serious of german producers will admit this and that's something.
keeping up to date is important and most people i know buy records to do that , but you have to accept that over the years the format has changed and now people use c.d. if they want to listen just at home.
vinyl has been a dj market for about 5 years now and the market is still shrinking , and that pretty much the size of it.
people jst generally don't have a turntable at home any more.

long answer sorry
i'll get my coat
