I enjoy singing karaoke on a weekend evening.  It's relaxing to sing the way I want without the vocal track.  Do you enjoy singing karaoke?
I don't but I know it's very popular in Japan, a place I'd love to visit someday.
I really enjoy the concept of creating a studio recording with my own voice as the main singer.  Let me know if there's anything with karaoke you are interested in!
Do you know anything about the history of karaoke? That's what I'd like to learn about some more.
Definitely - Karaoke started in the late 1960s and into the 1970s.  As stored audible material was beginning to be popular, many bands and musicians just made music recordings with no vocal track for individuals to sing their on their own.  
Oh cool, so it's not really that old at all. I wonder if there was anyone in particular that popularized it.
Not really - I think the popularity of it came from the entertainment one got from performing on stage and in situations where they believe they were in an actual concert.  With that said, karaoke and lip syncing are two different things.
That's true, karaoke is actually singing unlike lip singing, or is it lip syncing?
