The "Add to queue" action from the Artist's sheet and the Album/Genre/Playlist sheet should provide feedback that the button was selected

[Victor Thompson]

Currently when the "Add to queue" button is selected from a sheet the user does not know whether the action was successful. Other buttons for adding to the queue, for instance, collapse their current view. While I think a solution for this could be to close the sheet, just like the "Play all" button does--I think the better solution would be to have both "Play all" and "Add to queue" and the corresponding icon flash white for a short period of time when they are selected.
