Taylor fires up feud with Katy

TAYLOR Swift appears to have ratcheted up her feud with Katy Perry by making her entire back catalogue available for upload – on the day her rival released her latest album.

Miss Swift, 27, has been an outspoken critic of music sharing service Spotify, accusing it of devaluing artists by giving music away for free.

But yesterday she ended her boycott of the platform in a move critics suggested could take the spotlight away from Miss Perry’s new album Witness. The stars, pictured, are in a long-running feud believed to have begun as a disagreement over backing dancers.

Miss Perry, 32, said this week: ‘I wish that I could turn the other cheek... especially when someone tries to assassinate my character.’ Miss Swift’s management said she was making all her music available on Spotify to thank her fans for helping her sell 100million singles in the US.
