KantoPlayer allows you to do karaoke on your Mac. It supports almost all karaoke formats: MP3, MIDI, KAR, MP3+G, CDG, KFN, and MP4 video karaoke. It also allows you to record your voice over the song and convert your midi files to MP3 format. The software is free to try, but with a few limitations. The user interface has an efficient layout. Playlists can be created and populated with songs on separate panes, on the right side of the interface, where you can also build up a song queue. If you play a karaoke file, its lyrics will show up in the central region of the interface, but it is also possible to display them in a separate window, which can be useful if you wish to show the lyrics on a different monitor or with a projector.
