I really love his voice. I use to be a little iffy on it but now I just adore it. I smile a lot when I hear him singing. It's just so unique and soothing.

I can't really think of songs off the top of my head but his solos are always good. Happy happy songs really suit the sound of his voice cause it's got a playful tone to it but also I really think soft ballads suit him too. For example in Snowflake his voice just fits so well. I just melt when I hear that song

I really like Aiba's voice in Koe, track no. 9 from Dream A live album... He sings at the beginning of the song and his voice really suits the song's mood...

My ma once said that his voice sounded like mickey mouse. But I love his voice, it's fun and sensuous And I love his singing in Itsuka no Summer!

I just discovered JAM. Woah! It's so different from what you usually hear from him. It's interesting heh I'm still not really sure how I like it but it's definately got my attention.

I love Aiba's voice~
To me, it sounds kind of breathy and light.
I think he has the cutest voice out of the 5

It kind of suits him, being described to Mickey Mouse XD

His voice is lovely...its unique, eh? ^^ I love it when he sings Itsuka no Summer. Sounds so cute!!

His voice is really unique.^^ But I have to admit: when I first heard it I didn't like it that much.
But now, after listening to many songs, I really fell in love with it. His song friendship is great. And it wouldn't be as good with another voice.

I like that his voice is sometimes husky, and that he has a loud and genki voice.

I think Friendship suits him the best, the usual tension up and genki singing voice. Namida no Nagareboshi is also a good one, shows the calm side of him...he can go pretty low (as in pitch)

I do like Aiba's voice, because it's so distinctive. When you hear it, you'll know immediately it's him singing. I think it's soothing, in a way he has a really soft voice. Yeah I like listening to his voice.

I love his voice. I think its really nice, and unique. When he sings Itsuka no Summer, I think his voice is just so adorable (like him). ^^

I adore his husky voice! that was one of the things that got me to notice him out of the others. I agree with all of you when you say that he is awesome in RIGHT BACK TO YOU. I think he also sounds great in Modori Ame!

out of all the songs he sings, i luv Friendship, Itsuka no Summer, and Hello Goodbye!

At first I really, really couldn't stand Aiba's voice because of how husky it is, but after Hello Goodbye, I really started to like it more. It's pretty cute after you get used to it, and he sounds really hot rapping in Cool & Soul. I also like how it sounds at the beginning of Snowflake.

I like Aiba's voice because it's pretty unique. He's probably got the third best voice from Arashi in my opinion, behind Sho and Ohno. Actually, he's probably tied with Ohno, because it's hard to compare their singing voice beause they're so different.

I haven't really heard any of his solos(though I can hear his voice clearly when a few of them are singing together and I like that about him. ) , but his little part in La Tormenta 2004, ah, well, let's just say that I didn't listen to it only once or twice in a row. And also, his little bit in Sakura Sake. I wonder how I came to like him so much...it's probably because his voice grew on me so much that he's now second place.

i like aiba's voice on pikanchi double... his solo part near the end..
