Which single song best corresponds with its cover?

I've always felt that the 'Endless Sorrow' cover represents the song well.

I agree.

I think "BLUE BIRD"'s cover is very true to the feel of the song as well. Album-wise, "I am..." has a very ethereal, wistful feel to it and I think it corresponds well with the overall message of the album.
