Yes and, IIRC, McCartney bought them back a few years later.........
I don’t know why she thinks she would be able to own her music at a young age. The person who she is talking about is only 3 years older than her, so how did he con her?
That is likely what will happen in this case also.
Swift should stop emoting and start negotiating with Braun, who is more likely to make a deal than her old label was.
