I guess Apple could insert ads during the trail which would pay them next to nothing but would really represent want the service really is. So here is the thing, if someone discovers, listens to and downloads their music during the three months but leaves the service, they may actually buy it from iTunes to continue to enjoy it. Most song have a 90 second sample in iTunes which is half the song anyway. The more I think of it the more their position makes no sense. They have been making zero from Apple Music before now, if the hold out, they will continue to make zero. If they join, the relatively small number of buyers who will try out the service will have a chance to hear them and put them in their playlists. In three months the start getting paid for those that like the service and have discovered and continue to listen to them. Otherwise they could only keep the people who are on ad supported services that pay nearly nothing and would take a year just to pay out close to one month of Apple pay for the same # of plays. Apple's plan is a partnership that shares revenue. If they don't make anything, you don't and vice versa. They do still handle the processing marketing, and support for the free trail, so they actual have the only costs involved. Keep in mind under most record contracts, the artist would be charged for any free units, marketing cost, or other expenses incurred by the record company, and it would come right out of any royalties they were due. If Apple were to bill the company for its expenses during the trial, the artist would pay out of pocket for it. Just like they pay for placement in stores that still sell CDs.
You're making too much sense.
