For the less technically inclined: the folks at Deezer trained an artificial intelligence program with the ability to separate the voice and instruments from a given song; then they made the software freely availabe for anyone to use.
Given a bit of computer know-how, it was pretty easy to install and run on my Mac. Below is one of my tests using one of the all time greatest songs. It sounds pretty good, but not quite completely natural.
Any songs you’d like me to try out?
