I found another cool and fun karaoke software for Linux that I would like to share to everyone. It is called Performous and it's so far one of the best karaoke program that I've tried.
Performous (formerly known as UltraStar-NG) started as a clone of SingStar, a PlayStation music video game. However, recent versions of Performous has become a lot different than SingStar in terms of features like its scrolling notes and precise singing pitch display as a wave drawn on screen in addition to the lyrics. These will allow the players to sing without interruptions and to easily correct their singing pitch to hit the notes precisely.
What I really like most about Performous is its scoring system that makes it even more fun.
