Like I have emphasized, it's irellevant of styles. i.e dark, soulful ect. It's still D'N'B, reguardless of styles. So if a station indeed plays 'dark' and soulful' it's still D'N'B. There's no disputing that. Clearly. Again, if the Station played just 'dark', it would still be D'N'B. Reguardless. NOW, if the station actually played Jungle, (YES, Jungle) then it technically should be under Jungle.
In ealry days of looking for stations I came across Live365 and they have indeed a Jungle section. And guess what? it plays Jungle! and nothing but Jungle. You know, that genre of music that doesn't actually exist anymore due to being all of it existing between 90-97.
Still, there is a D'N'B section in Winamp and still isn't used. IF IT'S NOT GOING TO BE USED, WHY PUT IT THERE?. You'll find that's mornic and indeed ironic.
Again, Jungle isn't made anymore. Listen to what Jungle actually is.
You'll find that D'N'B followed on after Jungle with more tempo and more synths and programmable sounds....http://en.wikipedia.org/wiki/Drum_an..._drum_and_bass
