As part of a little research into word analysis and how effective it is (a few people can probably guess why I’m doing said research), I decided to analyse the reasonably predictable musical genre of nu-metal.
From about twenty minutes work came the Generic Nu Metal Analyser. Input some lyrics (proper English only – yes, that means you nu-metallers will have to learn to spell), and check out the results. It seems reasonably capable on the tests I’ve tried, but will undoubtedly give out false positives and so on. Give it a try though.
I would recommend Linkin Park and Evanescence as particularly generic nu metal songs that get picked up on (although they’re bound to have a song or two that aren’t so generic).
