Auto Queue on
Doubleclick on a File should add to the Playlist works.
why then add a other full Album which i have not select or Play.
should that be so?
Btw: You can inactivate the automated filling of the Play queue from:
TOOLS > Auto queue options...
Then uncheck "Auto queue enabled" and click OK.
Works as designed, auto-enqueue (add similar tracks) is enabled by default. Tested by deleting helium.json.

Depending on your Auto-enqueue settings various items can be added.
