Karaoke Forums

I'm new to using Karaoke at home.
I'd like to use a computer to play the songs to a karaoke mixer/amp.

What kind of software do you recommend for this?

Quality of music is really important to me so what kind of files should I buy?
Or how will I convert them when I purchase the different formats?

Thanks for helping the newbie.
