This is pretty simple idea. Here you can suggest a song that you think would be right up another member's alley (hopefully one that they don't know) and then they can suggest a song to somebody else. Please, only one song at a time (try to provide a link of some kind to the song) and do choose a member other than the one who chose you. If a week elapses and there's no response to a suggestion then anyone else can make a new suggestion.
I'll start the ball rolling... my suggestion is for Liftie:
