Mainly BP feed which I’ve honed down for 20 years soon (I think it started in 2005?) by adding hundreds of labels and artists. Then I try to find them anywhere else in this order Boomkat -> Bandcamp -> Bleep -> Junodownload. Only if all those fail do I buy anything on actual Beatport.
There was a time I had to limit myself to ten tracks a week, because that was the limit of what I can absorb so that I still know my tunes, now I struggle to find five a week I like. But in 24 years of DJeing I’ve never stopped buying tunes.
