Maaya Sakamoto - 私は丘の上から花瓶を投げる (I Throw a Vase from Atop the Hill)

and in second place would be Kiseki no Umi, also by Maaya. :love

this is so hard... ayumi has so many good ballads...
I think Dearest is something that will always be close to me. :*(

Ayumi Hamasaki - Rainbow,Forgiveness & Dolls.

Ayu's forgiveness, never ever (is this considered a ballad?), fated, jewel, you were, together when I love all of them

Gackt's Love Letter
Ai Osuka''s Kumuriuta
Utada Hikaru's be my last
shivers <3

if only for the season, here performed by ayu en gackt:



but the original is by B'z

Everything from Eiko ever beats everyone's everything lol

Anyway. I actually wouldn't choose Uchuu no hana as my fav.

Basically I don't like most people's ballads

So all my favs come from Ayumi, Utada, and Eiko Shimamiya and there's too many to specifically list.

There's other good ballads that I love too like ongaku from Maaya Sakamoto adnJASMINE's stuff and Ame no Orchestra by MUCC.
