At the mention of his master, Maul scowls but he doesn’t deny the words. “He didn’t like me indulging in anything that didn’t directly benefit him,” Maul says softly.

Things like reading and even watching the holonet were allowed because it gave Maul the chance to understand things like Sith history and how his master’s machinations would fit into the scheme of the whole galaxy. But music? No, that had no place in Sidious’ plans for Maul, and so it was frowned upon to even listen to.
