as far as gameplay music in kh1, i like the songs in Atlantica (Under the Sea) and that one in Traverse Town. For cutscenes, i'd say Friends in My Heart, Beyond the Door, and Sora's Sacrifice (I think that's what it's called. it's the one playing where he stabs himself). and in kh2, i like the one playing where Roxas finds Sora (it also plays when he finds Riku).
