WMP12 Playlist Frustration

In previous version you used to be able to be in library view and have a playlist open on the right. You could double click a song to listen to it on the left, decide if you want it in the playlist you're creating and if so, drag it over to the right. Now when you double click a song a new unsaved playlist of every song in your library view is created making it very frustrating to create a playlist.

I've seen people talk about the problem but I haven't seen any solutions. Anyone found one?

I'm aware of that possibility but it's not suitable for my purpose.

I understand that's the way WMP12 works. That's why I'm looking for a solution to the problem.
