When I'm listening to a long shuffled playlist, and I suddenly want to add to it by either searching or locating the proper playlist, I would like the newly added tunes to be shuffled-in with the still unplayed tunes prior to the addition. Currently I can append, insert, or enqueue, but these place the added tunes all together. I know that after adding I can press "shuffle" twice, but that may move some tunes I have already listened to past the current position (it can also move tunes I have not listened to before the current position).

Wouldn't it be nice to have "shuffled" in addition to insert, enqueue, replace, append?
