Does Kanye West own the rights to his music?

Could you please clarify for me if Kanye West indeed possesses the ownership rights to all of his musical compositions? It's a common question in the music industry, especially given the complexities of copyright laws and the various agreements artists often enter into with record labels and publishers. Does he have the full authority to decide how his music is used, distributed, and monetized, or are there any restrictions or limitations in place that could affect his control over his creative works?
