Karaoke is a versatile tool; it is a cultural sensation in Japan, and in Colombia many night clubs and bars use it to attract customers. The machines are not so expensive, and the discs are pretty easy to find and are affordable. Apart from the cost, the real function of karaoke is that it mutes the voice and shows one the lyrics so one can listen to the rest of the musical
instruments along with reading the words to pronounce or sing, depending on the activity. The misconception exists that karaoke is only for singing, which is pretty inaccurate due to the fact that one can also play an audio-book and immediately use it for reading the script.
