Metallica - King Nothing Lyrics Meaning

You're all wrong! This is a celtic teaching, It goes like this. In witchcraft you can cast spells as well as make wishes. A witch wishes to be king of the world, but forgets to be specific and he becomes king and there is no one around to rule. therefore his crown is worthless.

Another teaching is a witch wishes that every thing he touches turns to gold So not only his whole family, but every thing else he touches turns to gold too. This reference is also in this song.

The moral of the song and the celtic teachings is when you go to cast a spell, you have to be specific. (be careful watch you wish for)
