Hello.

From my console I try to call session.audio_key().get_audio_key(track.gid, file.file_id) but after some time it returns _queue.Empty.

What's the problem?

As a general troubleshooting, could you please check if the music is restricted by country or account type, or if it is available in a different codec?

@kokarare1212 It's not restricted as session.content_feeder().load() worked.
If I run it, I see that file_id is c04e355b9f4606b21f94b2a4de5db26aeca0163f (for .ogg 160).
Also track's spotify id 29d0nY7TzCoi22XBqDQkiP converts to 46982c56ce8f4470a377026e2fe1ac2f global id.
