Taylor Swift says a man who bullied her for years now owns all the music she has ever made after he bought the record label she was signed to.

Axar.az reports citing News Sky.

Scott "Scooter" Braun's Ithaca Holdings announced on Sunday that it is acquiring Big Machine Label Group, which released all of Swift's studio albums and owns her masters.

Swift left the label and signed with Universal Music Group in November because she says she knew that re-signing with the group that had managed her since she was 15 would only result in her not owning her future work.

Posting on Instagram with a link to a Tumblr blog, she shows a picture of Braun, with a caption that says: "This is Scooter Braun, bullying me on social media when I was at my lowest point. He's about to own all the music I've ever made."

In the blog post, the pop star wrote that she pleaded for years to own her own work but was instead given an opportunity "to sign back up to Big Machine Records and 'earn' one album back at a time, one for every new one I turned in".

"I walked away because I knew once I signed that contract, Scott Borchetta would sell the label, thereby selling me and my future," she said, adding that she had to make the "excruciating choice" to leave her songs behind.

"Music I wrote on my bedroom floor and videos I dreamed up and paid for from the money I earned playing in bars, then clubs, then arenas, then stadiums," she said.
