MongoDB EmbedsMany Query - mongodb

Question

So I'm using loopback to create a RESTful node.js API. I'm using mLab for my database. I'm trying to query data that is embedded inside of my Account model.
An Account model has a property called favorites which has an array of Songs.
Here is an example:
{
"_id": {
"$oid": "58512c1b7c05c491b2cff1f6"
},
"firstName": "Matt",
"lastName": "Thomas",
"username": "mattietea",
"password": "$2a$10$dcquPHK48H5Q7FcaTyzgf.vnrUOgKpBENS9fSa0hjoaASs0uyOWba",
"email": "mattcthomas#me.com",
"_favorites": [

]
}
I have an endpoint set up which returns all the favorites
api/Accounts/{id}/favorites
But I can't seem to query them. When I query all the songs from api/Songs it works but not when I query favorites.
The query I'm using is:
{'order': 'created DESC'}
I've tried multiple other queries, and none work.
Thank you!
