I hate to karoke! I can't sing a note. The term is also used by recording engineers when referring to an instrumental version of a recording. Do you like to karaoke?
Never been but i believe it is quite popular in Japan.
It's popular here in the United States. The concept of creating studio recordings without a lead vocal has been around almost as long as the art of recording itself!
Yea I can imagine, I wonder how old the concept is or where it originated.
I'm not sure of the date but many artists and amateurs perform where a full band is impractical so they use a karaoke recording instead. 
Thats pretty cool, what else is there to know about karaoke 
Well, karaoke is not to be confused with those who lip synch where a singer mimes to a song. lol
Haha yea my bad, whats some other interesting info tho
Well here's an interesting fact. Lip synching in film production is often done AFTER production has taken place.
