I recall this thread from sometime in 1998, when I was with someone that I am not with now, and how I long to back with that same person. Anyway, my choice for the sexiest Joni songs, having, ah, experience with filling the cd player with so many Jonis, is that the sexiest Joni song is all of them, given the right person and the right circumstances.
