Memorial address is loved by fans for these things:

Lyrics

Memorial address's lyrics are really deep because she talkin' about her father's death.
And death related songs are more touching than a bittersweet love song. I mean, you have lost forever from earth your beloved, as Ayu said 'You have gone to the place where we can never meet again'

Vocals

Ayu's vocals are pretty impressive in this song. When I've listen to Memorial address for the first time, I was speechless. You can feel her sadness through her voice. It seems like she let outside her feelings that she hidden in her own heart for a while.

Arrangement

Guitars, drums, piano. Three instruments for a simply amazing music. Them follows very well the power of her voice.

I know, it's pretty difficult describe that song (especially for my poor english skills lol)
but Memorial address is loved by a lot of people because is one of her few 'true songs' and that makes her more than a simply japanese-pop idol.
This is just my opinion, of course ^^
