I vote for Haru!
Her voice is the first I've ever heard that is so deep and unique!

Voted for Haru <3 She has amazing voice, but i still love mami more .love.

MAMI.
She has a really particular voice. You just can't miss it! .love.

I voted for Haruna since I like her voice.
Tomomi has a great voice, it even sounds like a chimpmunks from the movie Alvin but I find Haruna's voice more suitable for the main vocal and for their rock type music.

It's just that Haruna sings the most of their songs. And still props to everyone, all of their voice are beautiful.

I voted for Haruna not because she's the lead vocals but I really like her voice. I think it's powerful and I really like listening to it. :D Well, I like Tomomi's voice too. It's so cute but Haruna's definitely the one for me!

Haruna has a great voice, but I'm more fond of Timo's chipmunky voice, how it suits either an upbeat or a mellow tune.

of course haruna... though her voice get exhausted sometimes in their lives.. but she has unique voice that fits the band...

voted for Mami, leaves an impression after hearing her sing solo

Haruna for meee~ I love her voice so much!.love.

i voted for haruna. Not that she's the lead vocals but because it is different from the typical squeaky voice I hear from japanese bands and that is one of the reasons how I started to like scandal. Aside from her I also like Mami's. Their voice blend is such a melody to my ear. .smile. 

i feel so warm when i hear HARUNA's voice:3
HARUNA!!!

Voted for Mami because her voice is one I just can't help but love. Either because you don't hear it as often or it's quite unique, I love it when I hear it. It's low but boarders on a bit flat sometimes, which is why I think she does the best as the harmonizer. It's also kind of punky and fits in so well with jazz-similar songs like Ring!Ring!Ring! and Kagen no Tsuki. It's a genre I love. 

Otherwise, it's tied with Tomomi. I wasn't too fond of it at first but I grew to really love it. Especially when she's singing mid-tempo or slower songs, it's really sweet (Switch, Harukaze, One Piece, Bitter Chocolate, etc.). I could close my eyes and just listen... Her vocal range is also amazing, in my opinion. I don't know anything specific about vocals and stuff but I feel like her voice is more "open" than Haruna's, so I'd prefer her voice.

I voted for MAMI but SCANDAL would never sound the same without Haruna!

I vote for Haruna. It's her voice that got me into Scandal.
She has a hallow voice and it's very calming to her sing.

i voted for RINA....i like in "SCANDAL IN THE HOUSE" the part when she sings ......so beautiful voice  

RINA doesn't really get to shine in this.. but I'll still vote for Haruna either way.  

In general, nothing beats Haru's voice when she's at 100%, but Tomo gives me chills, I don't know.

I want to remark that Mami it's an exellent backing vocalist. She sings the lower voice, the higher voice, and has a great falsetto. I want a Mami in my band, and anywhere where I could be.

Haruna!!!!!!!!

btw, if you want to hear all their voices, watch/listen to Scandal in the house.

All their voices are amazing!!!!!!!

Tomomi's... Her voice gives me the most impact. I feel like she would sound great singing folk songs

I very much prefer (and miss) the younger, smokey version of Haruna's voice; and Tomomi has the best range, and her voice is the most distinctive in the group, and probably is the one that best defines the band's sound from a vocal perspective; but I voted for Mami as my favorite because she has a punk quality to her voice and vocal delivery.  

Since she doesn't sing lead that often, when I hear her voice on a line or two in a song it really stands out for me.  It has character.  Because her voice is so different from the other three, she contributes a lot to the harmonies in a way the others can't.  Her voice also sounds very distinct in comparison to the other J-Rock female bands I listen to.  If Scandal never existed and the four of them were singing lead in separate rock bands, Mami's voice is the one I would most gravitate towards.

Voted for MAMI. Partially just because she's my favorite member, also because I find lower voices more appealing and MAMI has that low voice I like.

Mami's. That voice made me a fan.

I vote for Haruna. Her voice is deep and unique.

I like Mami’s voice, her voice is punk.
Rina doesn’t sing very often. I like when she sings Oyasumi.
