Cloudfront Invalid Key when requesting track

[explaura]

I tried requesting a track like so:

spotify.trackUri(track, function(err, res) {
      if (err) throw err;
      if (!res.uri) return stream.emit('error', new Error('response contained no "uri"'));

      console.log(res.uri);

      spotify.disconnect();
    });

...however the track didn't play. I then immediately copied and pasted the generated URI into a browser and received the following:

Error Code: InvalidKey
Error Message: Unknown Key

URI:

The preview clip of this song works fine. Anyone else experiencing this issue/know what's going wrong?

Yes, they renamed it to track_uri2, (and seemed to have disabled the S3 bucket for the normal track_uri call), which will then serve you a encoded mp3, which so far hasn't been cracked yet.
I'm afraid you're out of luck.
I could find some discussion threads of a couple of guys trying to crack it (but like half of the comments are deleted), so maybe that helps you.
Also, it appears they added a captcha today, making this library (and the above mentioned fork) unusable without modification.
