My rankings are like this:

1. Ohno = his voice! And that's not just because he's my ichiban I was very impressed when I saw his performance in his solo Song For Me (concert) they way he dances like that and hitting the notes perfectly and I don't think he's lip-syncing...I thought dancing like that would get someone out of breath, but it didn't make any effect on Riida at all, did it? Sugoi na Riida, ne.. Anyway... as far as I've seen, almost everyone agree on that, right?

2. Nino = waaa.... my favorite is when he sings Niji! or any other slow songs for that matter.. (konseki, yume, Caramel Song..etc)

3. Sho = because of his awesome rapping

4. Aiba = unique voice.. but I don't like it that much.. gomen..

5. Jun = *no comment*

1. Ohno
2. Nino
3. Aiba
4. Sho
5. MatsuJun

1. Ohno-san .. of course... no question about it.
2. Nino ... love his solos ..
3. Aiba ..
4. Sho-kun ..
5. MatsuJun .. the "nose" sound, it's kinda................

1. Ohno (That's a given! He's so soothing to listen to. I wish he'll sing more solo ballads)
2. Aiba (I love his solos! That deep, unique voice )
3. Nino (He's the most musically talented)
4. Sho (Well, he is, more importantly, the rapper)
5. Jun (His singing is unexpectedly high...)

Ah, I'm being partial. But other than my 2 distinct favourites, it's hard to rank them!

Haha xD
1. Ohno Satoshi of course I just love his solos *o*
2. Ninomiya Kazunari I dunno why I like his voice so much.. maybe because of niji? or gimmick game? *-*
3. Sakurai Sho & Aiba Masaki - exact.. can decide, well I mean I don't really LOVE their voices but it's not bat either.. (still better than MatsuJun's voice xD)
4. MatsuJun.. sorry Jun but your voice is no-no.. though you have awesome laugh xD I laugh when you laugh xD

1. Ohno - who wouldn't love his voice.

2. Sho - i love his deep voice, very manly. I always wait for his part when listening to their songs.

3. Nino - he got a nice voice esp when he sing ballad esp in Niji. Just don't sing live coz he was off-key sometimes.

4. Jun and Aiba - there are times that I don't like Jun's singing voice but he's good in La Familia.

Other than their solos, I love listening to Aozora Pedal, Koe, Carry on, Blue...coz their solo parts on these songs are really good. You would really appreciate their singing voices.

1. Ohno

2. Sho

3. Nino

4. MatsuJun

5. Aiba

1. NINO! ICHIBAN <3 Enough said!
2. AIBA-CHAAAAN <3 He's just overloaded with cuteness and dork.
3. JUN 8D Can't get enough of his sexiness.
4. OHNO! Riidaa's the cutest leader ever!!
5. SHO! He's just so damn kakkoii when he raps, ne ne?

I really hope I won't jump to another Arashi member from Nino for my 1st placing because Jun used to be my ichiban when I was in the Junbait period.. D:

-hides and runs away-

ok,here's my list:
1. ohno: although i like sho the most but i must admit that ohno has the best voice in arashi
2. nino: he really has a great voice
3. sho: i like rappers actually
4. matsu jun: his voice not so good compare to ohno, nino and sho
5. aiba: his voice okay but i don't really like that type of voice

Erm:

1. Ohno - best voice out of all of them: so soothing and controlled!

2. Nino - I really love his voice, it's really sweet

3. Aiba - I love his voice

4. Sho - I love his rapping.

5. Jun - I'm really sorry Jun, but I really don't like your voice sometimes. It's kinda... nasaly.

1. Ohno- best voice, no doubt plus he really has good control of his voice
2. Nino- sometimes it's off-key and a little high in my opinion but his voice has the ability to touch your heart, seriously
3. Sho- loves the rap!
4. Aiba- his voice is really unique, ne?
5. Jun- I like his voice in certain songs but most of the time it's a little too high... gomen!

1. Ohno (no brainer!)
2. Nino (cute voice)
3. Sakurai, MatsuJun, Aiba

I'm indifferent about the last 3 so they're same rank, hehe. They all can sound very nice though, depending on the song. I love when Sakurai raps (but I'm ranking this on singing only).

1.Oh-Chan!!
2.Ninomiya
3.Aiba-chan
4.sho-kun
5.junji *sorry jun, love ur acting though*

Based completely off CD versions of each song and the one or two concert rips that I have...
My ranking order would be:
1.Sakurai Sho. I have a thing for deep voices. I loved his voice since I heard his little solo in Aozora Pedal and Can't Let Go, even though that song took a while for me to like. His raps are amazing too, but his singing voice makes me melt. Even though it's hard to understand him sometimes...I still like his voice a lot.

2.Ohno, in VERY close second because it's a hard choice. I love his solos and stuff, but I'd say I listen out for Sho's voice more, so that's what puts Sho on top.

3.Aiba, it's unique and I just liked it after hearing Friendship. And Also Nino I don't know which one I like better, but I do quite like both of them in their own way. Aparently Nino goes out of tune a bit...but I wouldn't know and I have absolutely no ear for music...at all.

4.Nino, way above Matsujun. Huge gap. But I'm not overly keen on Nino's solo voice, which is mostly based upon 'Niji'. I'm not fond of high-pitched voices. I love it when he sings with the other members though, when it's a bit more evened out.
Actually, I changed my mind. I actually like Nino's voice in his solos... Specifically 'Niji' and 'Konseki', though I first hated Niji when I heard it on the computer, I downloaded it and listened to it on my iPod and I instantly liked it. I surprised myself there.

4.Matsujun. (So far down the bottom it hurts.) I really don't like his voice at all in solos or in mini solos. There was a point in time that I tried to lie to myself and say that I did. But it's too big of a lie to hold up for too long.

Hah! It's so close to being in age order.

Everyone seems to have Ohno and Nino in high positions and the rest in lower...specifically Jun in last... wonder why...

1. ohno - this is unanimous.
2. nino - he has a good voice, its just ohno's voice is the best
3. sho - his voice is better than jun...
4. jun - by elimination
5. aiba - i do not like that type of voice
