I think there is a big difference between commercial pop music and the electronic dance music scene that even the legal professionis aware of
for 25 odd years there has been a culture in electronic dance music of mixing together tunes and advertising them by DJ’s mixes and pirate radio stations.
On this particular music scene the artists have wholly accepted this as a form of giving wider publicity to the music, as it is often otherwise shunned by mainstream shops and media due to its links with drug culture and its underground nature.
I’m not sure of the exact legal term (I think it might be called a “de facto” precedent) but as its been going on for years without the dance labels taking major action as a civil tort for loss of royalties.
I think some of the larger labels and big name DJ’s did try to clamp down on bedroom mixers in the 90s when dance music briefly went mainstream (in other words trying to create a closed shop) but it came to nothing.
many smaller labels aren’t registered with the royalty collection agencies anyway
TBH the copyright lawyers have far bigger fish to fry such as the re-use of commercial pop tracks and TV footage on youtube and other similar places.
