Evidently, starting next year, Swift will have the legal right to do something harmful to the owners of Big Machine Records- rerecord her old songs. The owners of that company currently have the legal right to prevent her from playing her old songs. There are many artists who I think have been exploited by the executives of their industry, but Taylor Swift isn't one of them. I expect that she was generously compensated for giving up ownership of those songs. If she wants to change the terms of that deal, the other parties have offered to negotiate.
