Luis Adrián Cortés Ramos ("Cortés") appeals from the dismissal of his contract and intellectual property claims against a variety of companies affiliated with Sony Music Entertainment ("Sony"). The dispute concerns an original song and music video that Cortés submitted to Sony as part of a songwriting contest sponsored by Sony. The District Court dismissed all of Cortés's claims. It did so on two grounds: that the claims were subject to mandatory arbitration under the Federal Arbitration Act, and that Cortés failed to allege facts sufficient to support his claims under Fed. R. Civ. P. 12(b)(6). Because Cortés has not appealed the ruling that his claims must be arbitrated, we affirm the order compelling arbitration.
