The National Karaoke League is the home of competitive, team-based karaoke in America. Every season, each NKL division host weekly competitions across the country for men and women ages 21 and up, in which league members sing their hearts out as members of "karaoke teams". Everyone in the host bar gets to vote for their favorite teams and performers across three rounds, and at the end of each season one team is crowned "National Karaoke Champions".
