I recently fell in love with Juana Molina's music. It is classified as folk, but I might refer to it as cocktail music. Of course, that is my own classification. Or 'bubble jazz' another singular classification.
Juana is an Argentinean native who spent part of her adolescence in Paris and is well known as an actress in Latin America. Most of her lyrics are sung in her native dialectal spanish - so I don't understand a word. She is compared to Bjork, amongst others, probably due to her mix of ambient and electronica. She usually mixes tracks, writes, and performs on her own.
