Jungle/DnB DJ/Producer here for the past 10 years. Juno download for anything I purchase. Email promo lists for everything else.
A lot of label owners (including myself) will email out new promo weeks before the official release. If you can help promote their music, they will add you to their promo contact list. I’m at the point now where I don’t need to buy anymore music and get stuff before most folks.
I still buy music when there’s something I hear that I must have, but not so much anymore.
Happy to answer any questions
