Since I made one for Super Junior, I decided to ask around and see whose voice stood out to fans when they first listened to DBSK’s songs. Here’s mine:
1. Yoochun
2. Junsu
3. Changmin (I sometimes got his voice mixed up with Junsu’s though, but as soon as I hear Junsu singing after his solo, I’d be like, no way, how can I confuse their voices o.o”? XD)
4. Jaejoong
5. Yunho (I’m still not entirely sure of what his voice sounds like really. He needs to get more lines!)
I dunno, I think some people say that Jae’s voice is really distinctive? That’s what my brother says anyway. But I found his voice just seemed to blend in so well with the songs, maybe that’s why Yoochun’s voice really stood out to me.

1. Jaejoong (I agree with your bro. but not because it’s distinctive it goes along with any genre of the song he sings. Plus I don’t just pick because he sounds different.-not intending any offense ‘just in case I want to include this’)
2. YooChun(he has a deep voice, and a different range when he sings high notes but often pitchy. o.o Chun hyung I believe should be the right person to use the word “distinctive” on, because his voice is really different.
3. JunSu (my second best favorite singer in the group. explanation to his place: nothing lol )
4.Changmin (Changminnie hyung has tremendous high pitches in their songs, but it’s somehow not that catchy when you get use to his voice. He’s good though xD)
5: YunHo (I’ve been protecting him from anti’s who hates his voice… *grr* He’s good in acapella. Though he raps most of the time, he could mimic a voice that seems like it was synced. That’s impressive like his voice in purple line. Since he raps most of the time his voice… is not much recognized.
ahah I’m talkative.. xD just wanted to share anyway. ^^ that’s my list
Thanks for sharing ^^. I agree Chun’s voice is really distinctive, I could tell him apart from the other members pretty much right away when I first heard DBSK’s songs.
Yunho has improved massively since debut. He has a nice voice, but I still don’t think he gets to sing as much as the others ;__;.
(and…hyung? Does that mean you’re a fanboy? :DD)
