var Services = {
	Pandora : {name: "ziggy", password: "stardust"},
	AppleMusic : {name: "steve", password: "jobs"},
	SoundCloud : {name: "bedroom", password: "studio"}

};

console.log(Services.Pandora.name);
console.log(Services.AppleMusic.name);
console.log(Services.SoundCloud.password);

public enum Service {

    Batanga     ("Batanga","Batanga","my_name","my_password",""),
    Calm        ("Calm Radio","Calm Radio","my_name","my_password",""),

    ;

    private final String svcName;
