Swift's letter caused Apple to promptly change its mind and compensate the artists. But last summer when Swift pulled her music from Spotify and voiced concerns about the way it compensated artists, the company largely ignored her.
Swift told Vanity Fair it was "ironic" that Spotify, which isn't profitable, ignored her while Apple listened.
"Apple treated me like I was a voice of a creative community that they actually cared about," she says. "And I found it really ironic that the multi-billion-dollar company reacted to criticism with humility, and the start-up with no cash flow reacted to criticism like a corporate machine."
Zing!
