JoJo & Taylor Swift bonded over label issues.

JoJo reveals she bonded with Taylor Swift over record label issues, years prior to Swift’s public feud with Big Machine Records over her masters.

Taylor's career did not take a severe battering like JoJo's, because Taylor's career was already highly established to epic proportions. When Taylor publicly outted Big Machine Records, they backed down, largely due to the astonishing power and support of her fanbase. As a result, she was allowed to perform her old music at an awards show. Taylor had the clout to fight back successfully. When JoJo had her problems with Blackground, all you heard was crickets.
