Unable to retrieve data store in ember

I am using ember and trying to use an adapter to get a json response for the first time. Although the data is there in the console log it looks like the model is not retrieving the data.

In songs.js router I return the model...

export default Ember.Route.extend({
    model: function(params){
        console.log("This. ", this.get('store').findAll('songs'))
        return this.get('store').findAll('songs')

    }
});

In songs.js adapter I have my call...

import DS from 'ember-data';

export default DS.RESTAdapter.extend({

    findAll: function(store,type,id,snapshot){

        return $.ajax({
        url: 'http://ift.tt/1RjByBK',
        dataType: 'jsonp',
        success: function(response){
            console.log("resp? ", response)
            return response
        }
        }).then(function(data){
            console.log("this is dfaataadgagafgaffg     ", data)

            return{
                    songs:  {
                        resultCount: data.resultCount, 
                        results: data.results
                    }
                }

        })

    }
});

In songs.js model I have the modeled response...

import DS from 'ember-data';

export default DS.Model.extend({
  resultCount: DS.attr('integer'),
  results: DS.attr('array')

});

I also defined the array transform...

import DS from 'ember-data';

export default DS.Transform.extend({
  deserialize: function(serialized) {
    return (Ember.typeOf(serialized) == "array")
        ? serialized 
        : [];
  },

  serialize: function(deserialized) {
    var type = Ember.typeOf(deserialized);
    if (type == 'array') {
        return deserialized
    } else if (type == 'string') {
        return deserialized.split(',').map(function(item) {
            return jQuery.trim(item);
        });
    } else {
        return [];
    }
  }
});

The result from the API is {resultCount:50, results: Array[50]} per the console log so I am unsure why this is not working. Any ideas?
