The performance came after Halsey defended Swift when Swift made a statement about Scooter Braun not allowing the pop singer to perform her own music at the show.
In June, Big Machine Label Group, originally owned by Scott Borchetta, revealed the news that Braun’s Ithaca Holdings agreed to acquire the label which included Swift’s entire catalog she released through BMLG. The back catalog Braun has now acquired from Swift includes her self-titled album, Fearless, Speak Now, Red, 1989 and Reputation.
Swift released a statement via Tumblr stating she learned about the news along with the rest of the world. However, a source told Billboard that Swift’s camp knew about the acquisition since when Big Machine had a shareholder meeting to discuss the deal.
Recently, Swift was named the AMA’s Artist of the Decade, but now the singer is stating she’ll be unable to perform a medley of her post popular tracks on television because of restrictions Borchetta and Braun have made.
“Scott Borchetta and Scooter Braun have now said that I’m not allowed to perform my old songs on television because they claim that would be re-recording my music before I’m allowed to next year,” Swift stated on Twitter.
She also announced that Netflix would be releasing a documentary about her life but the two men have refused to let them use her older music and performance footage for the film. Borchetta said to let Swift use her own assets as long as she didn’t re-record her new versions of her old tracks next November.
“The message being sent to me is very clear. Basically, be a good little girl and shut up. Or you’ll be punished,” the pop singer continues. “This is WRONG. Neither of these men had a hand in the writing of those songs. They did nothing to create the relationship I have with my fans. So this is where I’m asking for your help.”
The full statement is available below.
