Command not working when compiling but no error [duplicate]

I am super new to java so sorry if this is an easy answer. I have to write a code for class that would be used in a smart home type system. Right now i am having a problem with the stopping music command. When i respond Stop music when I run the code, nothing happens. Everything else works. I tried doing if else but then it gives me an error that says syntax error on token else while expected. While what?? I have no clue what i'm doing but here is the code I have so far.

import java.util.Scanner;

public class SmartHome {

public static void main(String[] args) {

        double temperature;
        String genre;
        Scanner console = new Scanner (System.in);


        System.out.println("Welcome Home! What would you like to do?");

        while (true) {
            String command= console.nextLine();
            if (command.contentEquals("Change temperature")) {
                    System.out.println("What temperature would you like?");
                    temperature=console.nextDouble();
                    System.out.print("The temperature is now: ");
                    System.out.println(temperature);

            }
             while(true){
                String input=console.nextLine();
              if (input.contentEquals("Play music")) {
                System.out.println("What genre would you like?");
                genre=console.nextLine();
                System.out.print("Playing... ");
                System.out.println(genre);
              while(input.contentEquals("Stop music"));
                System.out.println("Stopping music");

                }
            if (command.contentEquals("Close system")) {
                System.out.println("Shutting down");
                console.close();
                break; //end the system and stop the loop
            }
          }
     }
}

}
