Autofill queue by last.fm

I'm a intensive user of my local library, but I don't want to listen to a complete albums mostly. I prefer to listen "moods" or genres. In my old player: Guayadeque on linux, I had a function called "smart mode". There the queue were added three additional songs from the library based on the user behavior on last.fm, when the last song from the queue was started.

This is very interesting as backround music.
