With Hoster you can import the track they wish to sing and when they finish Hoster will delete the track from your computer.
To import the track, insert the CD, then in "Add Track" area at top of Hoster screen, click on the "CDG" button, add the track #, song title and singer's name, then click add track. Hoster will then import the track and add the listing in the playlist. You can even do this while someone else is singing.
