I don't get what you're asking. If you're asking if Reanimation was made only by Linkin Park... Take another look at the back of the CD case .
Most of the tracks featured an artist either singing/rapping, or a guest remixer. So no, Reanimation wasn't only done by Linkin Park.
Almost all the band members had to re-record some things, only Rob had almost no work to do on it . They still worked a lot compared to what some may think.
This poll makes no sense...you're asking for someone's opinion, while the answer is basically a fact... You should have asked it in a question form...
