singles
there's too many singles that I think should have been #1 but I'll just say

Ayumi Hamasaki - Daybreak

[sora-kara]

Albums:

Hajime Chitose - Hanadairo
the album is incredible. i have no idea how it only ended up with #4.

HALCALI - Ongaku no Susume
they're best album yet. but no one knows it exists. ;__;

CORE OF SOUL - 3
number 134 on oricon? what the hell is that about? this album is amazing!

Nobuchika Eri - nobuchikaeri
'nuff said

orange pekoe - Organic Plastic Music
fantastic album. fresh, invigorating, relaxing and fun! these guys are far too neglected.

Singles:

Takasugi Satomi - Hyaku Renka/Tooku Hanarete mo
Stunningly gorgeous ballad, beautiful covers, good other a-side, fantastic music video, a breath-taking remix, and #20 on Oricon? ROBBED!

Bonnie Pink - A Perfect Sky
Its a great single, and she was so hot and so on for all of the promotion. #5 is good, but #1 is better!

and so many more for sure., but this is what i can think of right now.

[Foxxy_Fuyumi]

CORE OF SOUL was great band indeed!! Unfortunately their oricon numbers were always terrible...I dunno why =\

[Northerner]

Ayumi Hamasaki - GUILTY
I can't believe her best album since MY STORY stalled at #2! This makes me wonder if there is in fact a huge disparity between what Ayu's overseas and Japanese fans like.

Suzuki Ami - DOLCE
This was, with the exception of a few tracks toward the end, unbelievably solid. She should be right up there with Ayu, Utada, Namie and Koda, but she's sadly not.

Namie Amuro - The Queen of Hip-Pop
Speaking of Namie, she should have returned to prominence with this album instead of waiting for PLAY to put her back in the spotlight. I still like PLAY better, but this was great too. On another note, I also think it's a travesty that Put 'Em Up flopped. If she was an American artist, she would have had a smash hit with that.

Otsuka Ai - Kingyo Hanabi (Single)
How could this NOT have topped the charts?!

MISIA - Eighth World
It wasn't perfect, but it sure is better than some things that have gone to #1.

I wish CORE OF SOUL sold better. It's too bad they disbanded - I loved their music!

Beautiful World/Kiss & Cry... that single was #3 its first week and #2 the second week... and it was in the top 20 yearly, but it never hit #1!
