I have not read the whole thread, therefore apologize if I repeat someone's argument.
I consider myself a Taylor Swift fan, and own Red and 1989. I like a lot about her. Liked her WSJ opinion piece where she withdrew from Spotify (well, I'm a bigger Apple fan than Swift fan as we will see).
First, I emphasize that Apple is negotiating a 71.5% payout, higher than the standard 70%, after the trial. So they recognized there might be an economic consequence to the three month trial. 1.5% forever, versus three months of a zero base should be considered a "rape of the treasury" by any thinking business person. Yes, let's put some skin in the game and make this work, it is no sure thing for Apple, coming in late, etc.
Apple has paid for the entire set up of this service, Apple Music, all the servers, account setup, advertising, negotiating with the music business industry, purchase of Beats. This is their skin in the game. No guarantee at all that it pays off.
Apple is a public company and has a fiduciary responsibility to shareholders, like it or not.
So, Indie musicians won't get any payout from July thru September. If Apple hadn't started this service, Indie musicians would not have gotten anything from the company. Ah, but you say all the paid Spotify will go on hiatus for three months and they will lose that revenue. The argument is false because it implies that Apple Music will be the 100 million paid customer success Apple has set as a goal. So, from 20 million Spotify payers at 70% to 100 million payers at 71.5% isn't a good bargain? This short sighted thinking may explain why the music business industry is so weak, but that topic has many more facets to explore.
For Indie musicians, you know this is coming, plan your life accordingly. It will be a success, and you will "sell" more music on iTunes during the summer. See you in September.
For Taylor. You have demonstrated a brilliance in navigating all aspects of your profession. I don't know for sure, but I don't think you have a disciplined understanding of economics (not just pontificating, BA econ, MBA).
Also, your music I love but there must be a higher level. So, now you are rich, go undercover and sign up for some philosophy, psychology, english, history and economics classes at Columbia or somewhere and come back in a couple of years and set new all time sales records for a recording artist. And Apple Music will be there to help.
