Karaoke is huge in Asian cultures. I've been to karaoke places in China that are as large as a mid-rise office bldg. in the US with enormous staffs and state of the art equipment. Filipinos are also the main ethnic group you see performing in bar bands in China and probably much of the rest of Asia.
I got Mrs. Lee a karaoke machine last Xmas. You can hook your iPhone up to it, look up the karaoke version of whatever song you want on Youtube and then have the lyrics stream across the tv screen, while singing along. Pretty cool.
