If you look at classical music, in Mozart's time and before, everything had to be heavily patronised by aristocrats, and furthermore audiences demanded to hear something new every time they went to the concert hall, or they'd feel ripped off. In Beethoven's time and onwards, when the music became more commercialised through selling sheet music and making more of an enterprise from concerts, we saw an explosion of creativity and also virtuoso talent, and audiences started to appreciate the music more as a permanent artefact, valuing the composition as well as the interpretation. Seems like commercialisation supported by copyright made for a more optimal appreciation/demand for music.
