// Except for the client list, the application is stateless server-side.

// master client.

// If more than one client thinks that they are master, whichever sends
// an action across first should cause the other to obey the instruction
// and treat the first as master.
//
// The master client is responsible for:
// 1. Playing the music
// 2. Keeping the server updated regularly about the current state
//
// This type here is merely used for validation of client state messages.
// Each client implementation MUST adhere to this spec.
