title: Can i play track in play.spotify.com?
body: <p>My problem is, I want to search for a single songs ( or many single songs in a array) and Echonest will return me a Spotify ID in a foreign_ID. Then I can use this Spotify_ID to continue searching for a desired song in Spotify library. </p>
  
  <p>In this example this returns Tracks : <a href="http://developer.echonest.com/api/v4/song/search?api_key=QR3H8MYBUZDYTDWUB&amp;format=json&amp;results=1&amp;artist=the%20Carpenters&amp;title=top%20of%20the%20world&amp;bucket=id:spotify&amp;bucket=tracks" rel="nofollow">http://developer.echonest.com/api/v4/song/search?api_key=QR3H8MYBUZDYTDWUB&amp;format=json&amp;results=1&amp;artist=the%20Carpenters&amp;title=top%20of%20the%20world&amp;bucket=id:spotify&amp;bucket=tracks</a> </p>
  
  <pre><code>{"foreign_release_id": "spotify:album:0RZyZDffrtXVREHqoREIuA"
  , "catalog": "spotify",
   "foreign_id": "spotify:track:4VdTKWly7revQ8VoncG43z",

   "foreign_id": "spotify:track:4lEJYHkieQi5LfyFrN5bel",
   "id": "TRTEGDO147B6E4E95A"}
  </code></pre>
  
  <p>When I attach the spotify id which i get from echonest's return to the play.spotify.com that becomes "play.spotify.com/track/4lEJYHkieQi5LfyFrN5bel" it doesn't work, i don't know why. When I attached to album or artist, it works "play.spotify.com/album/3jMQ6qZZASytoRwVBSRou9".</p>
  
  <p>I want to ask one more question: can I stream one track (one song) directly from spotify into my web application after I use the command: GET "api.spotify.com/v1/tracks/{id}" to get url of the track(the song)?</p>
