How does this Karaoke thing work

[dribgnikcom]

I've been downloading some Karaoke songs off the net and I've been singing along to them (Queen rocks).

How do I:

A) Make a Karaoke cd? I mean how do I combine the lyrics properly so it will play in the machine ok?
B) Is there a computer program that can emulate a karaoke machine so I can test out my Karaoke at home?

Thanks
