When done right, karaoke can be an art unto itself, combining great
singing with glorious stage presence. When done wrong, as it is most
of the time, it's painful and annoying. While Simon Cowell frequently
uses "karaoke singer" as an insult, sometimes the best musical moments
come from a person on stage with a microphone and words on a screen.
Karaoke can play a crucial role on television shows. Sometimes it's
there for a simple joke, sometimes it provides a chance to show off,
and at its best, it's used as a key moment in a character's emotional
development.
