What’s the difference between electronica music and electronica
As far as I know, any music produced by electronica music instruments or technology can be called electronic music. Thus electronica music must be a subset of electronic music. But electronica music also presents a wide range of music genres, and is listed as a top-level genre on All music. They both have pages on wikipedia, but the definitions are vague and unspecified.
What is electronica music exactly?
It used to be. Now electronica is a main sub-genre of electronic music, among others like Downtempo and Techno. This confuses me even more.
