I used to hate all of Party Queen except for call till I decided to sit down and actually "listen" to the album. Now, I've come to appreciate the whole thing.

I totally forgot to mention You & Me haha

It was such a total disappointment for me~ :laugh

Oh I forgot some songs...the next love and eyes,smoke,magic @_@

glitter - I didn't pay attention to it when I first listened to it, but at least now I can stand it without any kind of trouble
Curtain call - at first, I thought it was so... boring? but now I love it! It also makes me think of my daughter :)

Bold & Delicious! I HATED it so much, but the live versions made me love it!
And also Sexy little things. At first I thought it was pretty weird to mix electro-pop and charleston (?), but now I think it's unique. I haven't heard anything like it by any other Pop singer to this day. :)

Bold & Delicious and Pride, but now I absolutely love those songs, and I think B&D was my most replayed song at one point.

I have a few.

vogue
Poker face
MY ALL
Ballad
Meaning of love
SEASONS
INSPIRE
ourselves
Replace
fairy land- I really have no reason as to why I didn't like this song, as it's now one of my absolute faves
Independent
Trauma
Duty
Girlish

I know I have more but I'm not looking at her discography so those are the only ones that first came to mind

I used to hate Evolution but now I love it.

Ballads. I need time for them. But I can't say that I hated them. They were boring.

Another Song. I was so disappointed when I first heard it as I remember thinking "this doesn't sound Ayu at all" which was silly as I now don't feel this way - even if it isn't the most Ayumi-ish tune - and I can enjoy the song.

Same. It was my first Ayu song. I couldn't stand it the first time I heard it, MV for it didn't help either. I still wouldn't say I love it but I definitely enjoy listening to it now.

Voyage, Independent

I used to not like these songs since 2003 but I started recently to appreciate them a bit more.
