And that actually makes the previous stiffing of artists an even more raw deal. I had read elsewhere that the rate was rumored to be closer to 90%, and at that rate it would take about a 10 months of someone subscribing to Apple Music to pay out higher than Spotify Premium, which pays out at roughly 70% (considering 3 unpaid months).
If you make the same comparison with Apple Music at 73% and 3 months free/unpaid trial, Spotify at 70% and 1 month, it would take more than 4 years before Apple paid out more. If you think you'll subscribe to either for more than 4 years and you care about the artists, it might be worth it. But it's going to take a long time.
If that payout number is correct, a conscientious consumer might as well subscribe to Tidal (who pays out at a similar 70% rate), because they'd at least get access to higher-quality tracks and the artists aren't getting payed significantly more or less.
It does not at all seem clear that you're going to convert a ton of free users - like you said in a child comment, there are numerous other places where people can stream music for free. It seems like an admirable goal, but then that's how Spotify pitched it's model to begin with as well.
I was at a party this weekend with a bunch of 20 somethings here in Singapore - and that's all they used - Nobody even mentioned Spotify - they just logged onto the wireless and added their songs to the queue - it was slick and 100% free (to the user) - and seriously, I don't recall a single ad in 3+ hours.
