// Only change code below this line
function updateRecords(object, id, prop, value) {
if(prop != "tracks" && value != ""){
  object.id.prop = value;
}
else if(prop == "tracks"){
  if(object.id.hasOwnProperty(prop) == false){
    object.id.prop = [value];
  }
  else if(value != ""){
    object.id.tracks.push(value);
