hey I found this a few hours ago it's a program thats only 173kb that allows you to play Karaoke on your pc
download the second file
Then you can download songs that have the music and words included at
they are very small only 22kb
All you have to do is unzip the files with winzip etc and the open then using the karaoke player. To see the words press the karaoke button. It's also a good idea to enlarge the font.
I'm not great karaoke fan but it's seems cool anyway
