This from Eddy Cue, Apple's senior vice president of Internet Software and Services (Swift's missive at 4 a.m., reply at 9 p.m.):
We hear you
Apple will always make sure that artist are paid
Not addressed in the response is Swift's issue:
"This is about the young songwriter who just got his or her first cut and thought that the royalties from that would get them out of debt. This is about the producer who works tirelessly to innovate and create, just like the innovators and creators at Apple are pioneering in their field…but will not get paid for a quarter of a year’s worth of plays on his or her songs."
