Just adding, that, outside of Rowling, who I believe has a different contract than most authors due to the expanded Wizarding World and Pottermore, most authors themselves cannot quote their own novels online because that would be publishing part of the novel digitally and that’s a right they’ve sold to their publisher. The publisher usually ignores this as it creates hype for the work, but authors are careful not to abuse it.
But it’s also improved music in general. It used to be possible for an artist to make one or two good tracks for radio play and then create subpar filler for the rest of the album, but now all of the tracks of the album are sold separately so every track has to be of equal quality. Additionally you aren’t bound to just the one song played on the radio when looking for new artists.
