For me, karaoke was the absolute best part of the convention. I'd go so far as to say I spent a majority of my "event" time in the karaoke room.
However:
The karaoke line is horrendously long. This is to be expected, obviously, but if I'm considering putting in for yet another 1970s super robot intro, I'd be happy to know how long I'm going to be waiting. I think, if possible, a visible list (aside from the single physical paper copy) of what songs are in queue (on a TV as a scrolling list, or on a whiteboard even as just a number of songs-to-go-after-this-one) would be useful. Of course, I can see this would probably be a logistical mess given the current signup system.
Secondly, it was never very clear to me what the period was before you would be allowed to perform another song. Was it kosher to sing your song and then immediately put down another after you got off the stage, given the traffic flow and the inevitable 30-song buildup that formed by the time you did that? Or is it on a time basis? If it was stated, I never got wind of it.
Finally, finding youtube videos of some of the performances I liked is always fun, especially if it's my fat ass on stage blundering through an Isao Sasaki classic. However, the presence of these relies on someone in the audience being interested in recording in the first place. For the competitions - there are two if I recall correctly - is it maybe a good idea for the con to "officially record" the performances and put them online somewhere? Maybe to promote the contests themselves?
I did however have a question to go in with all of this - is encouraging audience participation during the karaoke contest frowned upon for any reason? I know using a lyric sheet was purportedly a "bad thing" during that event, but I wonder if I wouldn't be able to mount the stage and sing Kotetsu Jeeg no Uta while encouraging the audience to fill in the "ban-ba-ban!" and "dan-dan-dan-da-dan!" bits..
Obviously that last bit's just a curiosity.
