I think you need a Yobi original music contest. I know you have YobiSing. But that tends to attract not so talented people doing Karaoke. An original music contest would attract unique musicians in my opinion. And keep out those bad karaoke singers.
We're definitely considering it for Season 2 of YOBI.tv. Some sort of band, songwriting, or original music contest, or even perhaps more than one of the above, might just make the addition to the YOBI Contests.
But I have to disagree about YOBISing being Karaoke. All the performances on YOBISing MUST be original compositions. Take a stroll through the contestants - I think you'll be surprised at the quality of many of the songs performed!
