Does Beyonce own her master's?

Excuse me, could you clarify something for me? I've been hearing a lot of buzz lately about whether Beyonce actually owns the rights to her music, or specifically, her master recordings. Is it true that she doesn't hold the full ownership of her masters, similar to other artists who have faced similar struggles with their record labels? It seems like an important topic given the power dynamics and revenue streams within the music industry, especially when it comes to such a high-profile artist like Beyonce. So, does she indeed own her master recordings, or does she still have to navigate through complex agreements and royalties with her label?
