the simple answer is no.

of course you can play with all the softwares that you can get on the internet. even with cool edit pro 2 (now is adobe audition) or any other expensive studio softwares but the results are same. it wont be as good as the karaoke version and to be frank, quite a long way from that. karaoke has the vocal recorded to a seperated channel. where all mp3 has everything recorded to a single channel. imagine you're dealing with water colours. can you mix several colours up and then let's say, you wanna take only green colour out of it? this has been discussed for countless times already all over any other professional sound recording/engineering forums.
