It's the opposite of "nessicary". Duh.

Some people can be so thick.

Sorry lucifer_sam. What can I say? I'm as dumb as a doorknob.

'Indie' is a bad comparison, as it's not really a genre to begin with - it's just an 'idea'. A great deal of the sounds that might be characterized as 'indie' tend to have virtually no stylistic elements in common at all.

Aside from that, I'd say that there are probably more 'sub-genres' associated with 'indie' by fans of alternative music than there are sub-genres associated with 'metal'.

Yeah it is a catch all term that I probably should'nt have used but one that I cannot be arsed to change. To be fair though, you don't get 'blackened alternative' or 'melodic alternative' and i think that 'indie' sub genres are more easily delineated and make sense. Whereas a genre of a genre of a genre is annoying to me. I suppose it's because i'm over 30. Everyone I know over this age finds sub sub genres ridiculous and not as clear cut as they are supposed to be. It's only an opinion though and most new metal fans like to use these sub genres, so good luck to them.

There are so many genres because there are so many different styles within metal, and while i appreciate and understand genres for the most part, there are always genres that dont make sense or are just dumb. It's like with "Viking Metal", it deals only with a bands lyrical content and would be like calling a band satanic metal, or political metal.

In my opinion, genres are good for the most part because if i asked for bands similar to Arkhon Infaustus and someone just said Death Metal (or even just metal) it would take a lot longer for me to find what i was looking for then if they would have said Blackened Death Metal.
Stating a sub-genre name is also faster than going into a lot of detail and describing a sound.
It helps people understand what you like a lot better, and isnt that hard to understand.

lol! it was you lot in the 80s who started the whole genre proliferation thing! we just inherited it! shame on you!
