== Dark Ambient == 

 There is an entry on dark ambient here: 
 http://en.wikipedia.org/wiki/Dark_ambient 
 Which should probably be merged into the ambient definition. Dark ambient is a pretty large subgenre of ambient but it still belongs under the definition of ambient. The article could use some clarifications, mostly about it's origins. Any objections to moving the dark ambient entry over here? 

 Also, I'd like to add mention of Tangerine Dream. They had huge influences on ambient even if they were never called ambient themselves.
