So we see who is best 
Does yours have configurable appearance, colors, font, text formatting, frame layout, Lyric charset auto-detection, support .kar and .lrc file formats, mp3+g, wma+g, wav+g, support for zipped cdg+mp3, support for Thai, Chinese, Japanese and similar languages? So we see who is best now? Sorry I couldn't resist *duck*
Using GameEx for Karaoke is better IMHO. I think a playlist is a cool feature at parties, for picking a bunch of songs to do. Perhaps you can add that feature to your stand alone player?
I'm starting to feel ashamed talking so much about Karaoke
