Hello,

First of all thank you for the excellent work with the go-librespot.

I have a question rather than an issue:

When I start my Spotify client and connect it with go-librespot, everything works perfectly. However, if I store the last played status using TinyDB and try to initiate playback without first connecting via the Spotify client, I encounter an exception:

anic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x48 pc=0x901210]

goroutine 1 [running]:
go-librespot/tracks.(*List).AddToQueue(...)
	/home/myhome/Repository/myproject-librespot/go-librespot/tracks/tracks.go:222

main.main()
	/home/myhome/Repository/myproject-librespot/go-librespot/cmd/daemon/main.go:462 +0x4e7
exit status 2

Basically, my question is: Is it possible to start playback without first connecting through the Spotify client?

Thank you for you time.

The problem is that you are adding something to the queue without having a context initiated, I have mitigated the issue by not crashing the player, but I don't think what you are trying to do is supported by Spotify.

You can try to play the song directly without adding it to the queue.

Hi,

Thank you for the update, the patch solves the crash of the player: "WARN[0171] cannot add to queue without a context".

About the queue, I will follow your suggestion, before to have a context, playing directly works perfectly:

curl -X POST http://localhost:3678/player/play \
-H "Content-Type: application/json" \
-d '{"uri": "spotify:track:..track_id...", "paused": false}'

In conclusion, to my original question the answer is yes, :-), we can play directly without first connecting via the Spotify client.

Thank you once more.
