While there's no press release or public statement to support this move, Taylor Swift's record label, Big Machine Music, has removed all of her music from the streaming service Spotify days after the release of her new album, 1989. Spotify has publicly responded on their site:
We love Taylor Swift, and our more than 40 million users love her even more – nearly 16 million of them have played her songs in the last 30 days, and she’s on over 19 million playlists.
We hope she’ll change her mind and join us in building a new music economy that works for everyone. We believe fans should be able to listen to music wherever and whenever they want, and that artists have an absolute right to be paid for their work and protected from piracy. That’s why we pay nearly 70% of our revenue back to the music community.
