Looking for better playbacks

[classic]

Hiy boys and girls.
I need your experience.
I´m looking for a software that should bee able to do something like this.

I put in a normal music CD into my computer.
The software plays it, in the way like windows mediaplayer but removes the vocals as good as possible, so you can sing to the original music.

Best would be, without costs.

Did anybody has got an idea

Thanks a lot.
