If a big plagiarism scandal hit the music industry, people will change their minds. From then on, bands that imitate and admit their influences will be regarded as unimaginative and untalented.
Musicians that don’t (openly) wear their influences and might not be that exposed to music, challenging themselves to create new sounds from real life will get a pass and even be well-regarded.
Musical originality becomes a big thing, becoming an improved version of rockist criteria where the musician has to come up with its own ideas and sounds to avoid accidentally plagiarising another’s work.
The standards would be far higher, favouring mathematicians who rarely listen to music over singers that wear them. Mathematicians making music isn’t new, dating as far back as the 60s but will proliferate in light of the greatest music plagiarism scandal.
