i think the most emotional ayu song for me was M. i would sit in the dark and listen to it and just close my eyes...the buildup in that song is so intense! and then at the end it all just fades away
i was actually thinking about this the other day when walking to class and listening to my MD player! I was listening to who... that song always makes me feel nostalgic, like her voice is asking, reaching for something...makes me think.
