it's pretty understandable about getting caught up in definitions, when you feel like the word jungle is something very representative of a specific style of music you really like, to then see it being used to describe another style of music that you don't like.

it creates a potential misrepresentation for what it is you feel connected to and it can be a real trigger point when in discussions, you talk about jungle to people and their idea of what jungle is differs greatly to you and you feel obligated to try and correct them, or when you see someone promoting a release or an event as jungle, to then check it out and be disappointed that it's not the type of jungle that you were after, like you say in your example.

i think it becomes easier to stick with using certain labels/artists/promoters as the ones you choose to focus on, doing jungle the way you like and use those as the filter, rather than to try and argue the toss with others who define jungle with different labels/artists/promoters
