I love music (and am a musician), but I disagree that good music is scarce. Part of the issue here (among many others) is that music is fairly "evergreen", and certainly much more so than apps. Zillions of people are still listening to the Beatles and Bob Dylan (two examples of "good music") more than half a century later. I worry that the ever increasing catalog of recorded music is making it ever harder to gain mindshare as a musician.
