how can people hate immature and ever free is beyond me LOL
(no offence, i just happen to love those two, but everyone has their own taste!)
I'd say...
1) teens
2) FRIEND II
3) PS II
4) HANABI II
5) from your letter (tho i love the fanmade remix)
yeah i'm not a fan of sequels lol.

omg..why everybody skips Dolls? This is one of my favourites from ayu.

ok..five songs:

Love ~since 1999~
Trauma (sometimes..it's just annoying)
Flower Garden
Dream On (I don't skip it but I never really listen to it..it's just there)
Why? (I like the verses but the chorus is so generic and Juno is sooo annoying)

Greatful days
Beautiful Fighters (MSTRKRFT remix is a gem, though)
Melody
What is forever love (beautiful instrumental, alas flawed by Urata)
Sunrise
etc.

I do not skip these, I simply omit them while transferring the albums on my MP3-Player but they are granted cordial accommodation on my HDDs (for archiving purposes), nonetheless :D

Obviously you're talking about me since I'm the only one who mentioned ever free. I love that song, I didn't say I hate it. I listed the songs I skip because I overplayed them and heard them too much because that's how much I like them.

Justice for Dolls. ;_;

Ignoring interludes and non-album songs:

1. Greatful days: Annoying, below average summer trash
2. kanariya: I will stop whatever I'm doing and walk to my CD player and stop the album when this is about to come up. I can't stand the cheesy arrangement, thank god there are many good remixes that do this song justice.
3. call: I can't wrap my head around why this song drives me out of my mind.
4. It was: Meh. So bland.
5. JEWEL: I've never figured out what makes most people love this song. It does nothing for me, boring throughout.

I won't include album tracks on her 5 first albums as i don't listen to them that much.
From newer albums, here are the parts i skip.
1) Bold & Delicious : Hmm YAYAYA GAGAGA... NOOO!
2) Party Queen : Please no.
3) Humming 7/4 : Only like the bridge.
4) Lady Dynamique : Boring.
5) The next love / Eyes, Smoke, Magic : Never do that again. Please.

1. HONEY
2. Bold & Delicious (..no just no :()
3. Humming 7/4 (too long to be a full song and quite annoying..ayu should've kept this as an interlude)
4. no more words (this song just keep draggggggggggging on and really boring)
5. OVER (see above)

1. NaNaNa (Timmy's annoying in this song, and I don't like the English lyrics)
2. Eyes smoke magic (least favorite song)
3. Voyage (never understood why this one was so popular I find it boring and the PV is my least favorite as well)
4. Return Road (Just never really cared for this song)
5. How beautiful you are (a boring ballad, PV's decent though)

Love ~Destiny~
Curtain Call
How Beautiful You Are (mostly skip it anyway)
Fly High (same as above)
Kanariya

01. Sunset
02. Ivy
03. FRIEND
04. Thank U
05. blossom

Two of us is a wildly underrated track. Both HAL's Mix and the original.

So many songs I love in this thread, lol... but then so many songs I TOTALLY understand skipping. XD

1. LOVE ~since1999~ - I really only like LOVE~refrain~ out of the whole series, but tsunku's terrible, terrible voice just makes this one absolutely dreadful. The live version on ayu ready wasn't bad though...
2. from your letter - Meh. I like it more as time goes on, but I still usually skip it.
3. Close to you - zzzzzzzzzzzzzzzzz. The slow, sloooowww vibrato is just... not pleasant.
4. Sweet Season - goober music. >_< The arrangement is just so homogenized, it's like the song is lost in a fog. I was really hoping for more from the same composer as "sekai ni hitotsu dake no hana"... although the more country-ish mix, which you can sadly only hear in the other cut of the video, is much nicer. Not very ayu-ish, but much nicer.
5. Present - It was already very dated sounding in 1999, and her "for the fans" songs tend to be my least favorite song on every album on which they appear, they sound kinda disingenuous in general.

"Two of us" is pure magic. Alas, it's so easy to overlook this song :( Really love this song plus it always reminds me on DJ Amaya.

1: Eyes, Smoke, Magic
2: Happening Here
3: Boys and Girls
4: Humming 7/4
5: Thank U

In my opinion...

Beautiful Day
GUILTY
Disco-munication / Jump!
Lady Dynamite
Thank U

1. the next LOVE -oh no I don't want to hear that
2. EnergizE -hate the music..
3. 1 LOVE -wild Ayu >.<
4. Trauma -boring
5. still alone -weird

Carols and Humming 7/4 - never been much of a fan of these songs...
You Were and Greatful days - a little bit boring these songs...
Unite - I´m sorry, but not catch...

P.S. II
Dolls
Close to you
Two of us
teens

These are the ONLY songs I do not like by her. Everything else is absolutely wonderful~ <3!!

Oh yay, statistics!

The eight most-skipped Ayu songs are:
1. Humming 7/4
2. Eyes, Smoke, Magic
3. from your letter
4. Thank U
5. Dolls
6. Greatful days
7. NaNaNa
8. Two of us

I have to say, honestly, there's alot about this ranking that surprises me lol.

Humming 7/4
Basically all of Party Queen
Montage
countdown
Last Links
Happening here

Other than those, I can't say that I -always- skip any other songs. I'll skip some because I'm not in the mood for them, but not because I dislike them.

I'm always surprised how many people on AHS dislike ANGEL'S SONG. It's one of my favorites haha. The PV on the other hand...
