I am looking for Karaoke songs that not only have the words but I also like it when a video plays in the background. I need these songs so I can mute the voice for regular Karaoke, or use the voice when people just want to sing along.

I know there are the VCD formats but I also heard that DVD formats have background video but I don't see this as true. Every sample I see with DVD only has the words? So I am a little confused.

Which format should I stick with for video AND words? Also, where is the best possible place to purchase these formats online? I am trying to get the professional sounding song also. Are they just remade or are the songs the actual recording? Anyone know anything about Karaoke music and which is best?

Thanks!!
