Nouvelle Vague means what depends on which side R U on.

Ever heard some French musique, such as Laurent Voulzy's Amelie Colbert, Enzo Enzo's Un Amour Humain, Willy Denzey's L'allumage, etc, very fine musique. (this section's simply a piece of shit!)
Found there's something different than average English pop songs- the ambience of musique, just like Italiano musica (my favourite), every language has its own certain ambience, Italiano strong, French soft and flowing, as to English... errr... ?! I've already been so numb for long, cannot find as many pleasure as in other languages. (this one, too. never mind... hehe!)

Right, Nouvelle Vague: French group, with very fine female vocalists(not for they're French beauties, but their beautiful voice), New wave, Bosa Nova, sometimes Jazzy, always smooth and tranquil, although most of their songs are also written in English, they sing songs in a peculiar French way,
by listening to their musique, will feel comfortable, and trendy, and poncy?! and whatever it is, cool by all means. Once you listen their works, you'll definitely be addicted to'em.
