But sometimes a karaoke show gets dull and you don't know why. I think every show takes on a life of its own based on the energy of the crowd and the song selections of the performers. So you can help resuscitate a defibrillating karaoke show by putting in a slip for a song that changes the pace. If the show is dragging, pick a fun dance song to get everyone on their feet, or a karaoke anthem that you know will lead to a roaring audience sing along. If the heavy metal selections are getting tiresome, throw in a mellow oldie to refresh the mood of the show. You'll be helping the DJ and helping the show if you create variety in the musical genres.
