ayu's Depend on you.

I chose it only because I've never put a song on repeat so many times in my entire life.
And I wasn't an ayu fan when I heard it since it was the first song of ayu I've heard.
However it was kumi's real Emotion who got me to jpop in the first place, but I didn't repeat over that song too much.

It's very hard but this I think is my #1. It's just so unique and amazing, I love every bit of it...the lyrics are so meaningful too.

Other picks I love in this thread were M, First Love, and Final Distance. All very amazing and in my top 100 of all-time Jpop somewhere, methinks.

Here are others that come very close to best song in general ever:
BoA - Kiseki
Namie Amuro - Chase The Chance
Koda Kumi - Yume No Uta
Koda Kumi - Hana
Nanase Aikawa - Yumemiru Shoujoja Irarenai
MISIA - Hoshi no furu Oka
Mai Kuraki - Perfect Crime

And I could go on and on and on :P

MIRRORCLE WORLD

AYUMI HAMASAKI - talkin' 2 myself

This is the greatest song ever!

(>.<)
hard ... hmm

Who ~ Ayumi Hamasaki

for the simple reason that I've never got tired of it. it has a special meaning for me.
such a beautiful song with beautiful lyrics.

ourselves by Ayumi Hamasaki

It's the song that got me into JPop and I've never gotten tired of hearing it.

It's pretty hard to pick the best one but I guess I would either say Hitomi Shimatani - Destiny ~Taiyou no Hana~ or Ayu's A Song For XX.

My favorite song of all time would have to be Be My Last by Hikki. I don't know, when I first heard that song, I thought it was really boring, and unlike her. But then, the single was released, and I REALLY changed my mind. The lyrics are so beautiful and the guitar/piano mixed in the chorus was really melancholy and sad. I've played this song more than any other and it really played a big part in my life.

Other honorable mentions:
FREE FREE by Ami Suzuki
Automatic by Hikki (first J-Pop song ever)
still alone by Ayu
Fly to me by Chihiro Onitsuka
infection by Chihiro Onitsuka
Discovery by BoA
tears by Ai Otsuka
Innocent Blue ~Chi Hate Umi Tsukiru Made~ by mink
