If you spin and use youtube-dl to build a crate, we all know, and we don’t respect you. You might win the crowd, but the people who actually bought into their profession and contributed to the community are also in attendance, and are very aware of your intrusion. You will quietly lose gigs without any explanation, and assume promoters simply can’t see your genius until you’re furiously working on 100 precious listens on SoundCloud. Fair use sampling? Go nuts and clean it up after youtube-dl. Five minute record? Make a Beatport account and get it overwith.
