How to get the auth token?

[tomo0300]

Heyy,
I have SC Go+ and would like to download all the songs - including those contained in Go+ - in full length. So far they are all only 30 seconds long.
I think I need to set my auth token for this, but I'm not sure if that's right and if so, where I get it from or how I generate it.
Or is there no way to download all the songs with your tool? (That would also be fine and should not sound mean :) )
