partly I have to agree with Mich though ^^ You are really the loudest in the chorus, and I guess it's so obvious because you always sing the solo-lines in the chorus, so people kinda remember how it sounds, and recognize it in the group parts...
you wrote you turned the others down so it doesn't outmax, right? this is actually what you're supposed to do, BUT, you should probably not only turn just all the other singer's volume's down, but your own too ^^
but i wouldn't say that because of this the mix is horrible ^^ i guess, if you realise that you really might be a little louder than the others, you could think about changing this in the mix, it's a thing of 1 minute to do, and maybe 5 minute to export and upload, so... i guess it would be a fair act :)
and kia really sounds a bit similar to AC's voice XD
other than that... ugh... you all made me listen to the most boring u-kiss song i've ever heard :( just to comment on here! haha.
not that i like any other ukiss song, but this one's really boring to me kekeke *runs away from all the u-kiss fans now*
