Probably because the scene it accompanies is so much more effective. The 1000 words sequence tells the whole story of Shuyin and Lenne and genuinely makes me care for them, more than for that convoluted romance between Tidus and Yuna the game before, all without a single line of dialog. Suteki Da Ne is just a really awkward sex montage.

And D, yes, Koda Kumi's voice does weird things, but at least she has a beautiful timbre. Jade sounds like a chipmunk. I guess that would make RIKKI a sugar-glider...
