Horizon is my favorite Carpenters album. In my opinion, Karen and Richard never sounded better than they do on this album. I would usually say that I love both sides equally but for purposes of this poll, side 2 wins by a hair. Solitaire is my all time favorite Carpenters song and I Can Dream, Can't I is number 3 on my personal list. Everything else between sides 1 and 2 is a tie.
