I can't agree with all of this. We have multiplatform open source DJ software for free, anywhere selling tracks gives you DRM-free files, there's lots of online record pools, Soundcloud/Bandcamp/etc. have massive amounts of free downloads, and if it comes to it tools for copying music from Youtube/Spotify/Tidal/etc. are not hard to find or use. It probably took more effort for Girl Talk and 2 Many DJs to obtain their source material then it would for an artist to do similar now.
