From Beats Music support page:
We are committed to making digital music more lucrative for the artist community. We pay higher royalties than the other services because we are a paid subscription-only service (in other words, we have no free version of our service that we have to subsidize).
We are also proud to be the only service that pays all our content creators equally. Nobody apart from iTunes has ever paid indie labels the same as major labels. We’re doing that, because we believe all music has value. We designed the service with artist input from the very beginning, starting with Trent Reznor. Additionally, Beats Music knows that an artist’s most valuable asset is their connection to fans, and we will help to encourage and strengthen those relationships through promotional and data sharing programs. link
If true and even if by just a bit, Beats Music might ease the conscience of guilt-ridden users of streaming music services.
