how can i change another guy singers with mj's voice on audacity?

why are you doing that? Just wondering. I don't know how to do it. Are you curious to see how the song would sound if Mike sang it? Good luck with that one, I'm not sure how to answer that question.

I got that program just yesterday. :)
So I can tell you later on.

it is very hard question by the way i will look for it and tell u later.
