I think ya'll need to use a little common sense hear. Clearly there is too much going on with Mike's vox. But maybe in a relationship with the rest of the track mixed down properly it plays out well. These guys are professionals, so clearly if they had effect on it there would be some justification behind it. I wouldn't freak just yet.
EDIT: Oh yea, and if mike thought his VOX were complete garbage he wouldn't have edited them in that way, because they don't in anyway enhance his sound vocally, so there has to be a point for it. Wether it's just for style or whatever, it's not to hide his supposed lack of singing talent.
Like someone said earlier, they put the stems on the shitty site like that, to help the people without editing software to remix. Obviously we would rip the stems off the site anyways, and once you're done just upload it back to the site. Simple as that. Plus the music has been up for like 10 hours. I'm sure the minute Mike put it up he wasn't just staring at the screen like us fans trying to figure out solutions. He was probably like "did it get uploaded? sweet, i'm going to bed later." I think the fans get a little to comfortable with this assumption that Linkin Park must cater to our every need and complaint. Just be glad they are still churning out music for us and attempting to do something sick like this remix contest.
Btw, the song clip to me sounds like an intro almost, and it sounds almost as if they edited things around to fit the clip so that people couldn't tell if it was the chorus or not. I sounds like it "could" be the chorus but it also sounds like it could be anything else.
