omg i totally agree chandrachan!

I tried to sing along to both of those and I fall behind ayus vocals so quickly :D

Still Alone, heck any I Am... song if I'm not warmed up properly. I haven't attempted Fly High but that is one I need to master (Is proud of being able to sing to Evolution and Ourselves)

Because of high notes?
None..
because of speed of some of them? Inspire in some places (I'm getting better..), Evolution, Ourselves and About You

Apparently I'm one of the only ones who must find evolution quite easy? XD

There aren't many hard songs for me lyrically since I sing along all the time and pronouncing Japanese on the spot isn't a challenge for me anymore. When it comes to high notes I just change the pitch - even with the instrumentals it still sounds fine.

everyone's "hatin" on M!!! i love singing it at karaoke! sure my throat is destroyed in the process but.... evolution is definitely a challenge... but every time i try it, i get more and more "slightly less sucky!"

M its really high and uh...evolution (Its too fast for me) and the chorus of A song for XX (cause its fast for me too)

yeah at first the shiawase part was hard for me but later I could sing it...well...XD

Mirrorcle World Chorus makes me confuse LOL
and SURREAL sometimes, too
evolution is easy

Mirrorcle World, evolution, SURREAL

D: Her ballads are pretty easy XD!

Fly high (rap part) and Until that day... are difficult for me to sing

You're not the only one, i love to sing evolution and find it quite easy to sing :yes

lols i'd say Talkin 2 myself...
dat sounds really fast =\

Hardest Ayu song is A song is born wtf man that song is super high... M too.

if you're talking about speed, then it's Fly high, until that Day... I think that's all.

I'm a guy who uses falsetto when I sing so maybe that's why.

i think moments?
moments chorus part the pitch quite high imo,
well, other than that, i think evolution is very difficult to catch the exact phrase that ayu sing .. she "rap" so fast o.0

kanariya
M
a song is born (damn these two songs are continuously in the album i am)

Kanariya, NEVER EVER(last part), Fly high, ...

I'm practicing to sing correctly the evolution but still I still forgot to mention the particles.

INSPIRE. the lyrics are even more difficult to catch as compared to evolution lol
and love ~refrain~

any song is difficult to sing if you start a pitch as high as hers :D

for me
1. evolution
2. for my dear
3. signal
4. a song is born
i think those songs very hard to sing

I think I've been listening to evolution and Until that day... to much? xD I really don't have a hard time with them anymore, I used to, but I guess I've gotten used to it. The chorus is fast, but I manage to keep up 8D Yay!

But kanariya is difficult I find... I haven't really been paying attention to any other.

Duty...... she reaches such HIGH notes in the chorus... you have to be really good to make it that clear and balanced. omword... crazy.

still alone is pretty hard for me to sing along with as is a song is born.

kanariya

and still kanariya...... XDD

Man this song is killing me! X_x
