I probably do, on average, £150 per week on new music. I have bought 'new music' every week since about 1985. The new music I have bought has turned into Old School - be it Hip Hop or Dance. If I hadn't bought new music, I'd have no Old School music today.
Of course not all the stuff I've bought has weathered the test of time, but if I've really made a mistake it goes in one of my little spring clean ups and makes space for some more new music.
For me, the vast majority of new tunes have their own little memories - be it that I have tracked them down after hearing them out or hearing the first time through a pair of headphones in a shop - and thinking "yeah, that rocks!" Then seeing how well it works when played out.
I'd say any DJ who doesn't have an open mind for new music is missing a trick, and as far as I am concerned, some of the tunes I bought this year will go on to be classics in years to come.
So, basically, yes, I buy new music - and always will.
