In your previous post all you talked about were the record companies. I won't go into the fact that today more than ever artists are putting out records on their own, with their own money without the backing of a label at all. There are several revenue streams for music artists, one of which is PUBLISHING. Publishing royalties are a huge part of income for any artist - these are independent from songs or records sold. These are paid out each time a song is played on the radio, TV, in a movie, a commercial or streamed.
So, what most people don't understand in this thread is that no artists will be paid any writer's/publishing royalties on anything streamed for 3 months. It's pretty crappy really as Apple can way more than afford it.
I think a great solution and compromise for all involved would be to give the free trial to all but retroactively pay all royalties based on subscribers that sign up with Apple Music once the trail is over. It's not perfect but it is certainly better than paying the artists nothing.
I would be shocked if the dollar amount of the royalties was over $500 million for the 3 month trial period. As we know, that is less than pocket change for Apple to do the right thing here.
