Google Music with .NET - Fetch a Track

Question

I am building a mini music player in .net for google music. I can get the playlist(s) from here. And I can see the playlist id, but how can I get the individual tracks from the playlist?

{
 "kind": "sj#playlistList",
 "data": {
 "items": [
 {
    "kind": "sj#playlist",
    "id": "935bfa54-36e4-452c-aa20-56c2835cb889",
