Here is a question we have heard often... Can you take off the lead voice from any song? No.
There is no such a magical software or hardware which can do that, no matter what you have heard or read on the internet... If that myth were truth, we and many other people would have backing tracks of any song in the world and, even worst, we couldn’t do this for a living!
This is a very slow work consisting on recreating the original song recording one by one each instrument, most of them virtually from a keyboard, as close as possible to the original song.
