comme il faut

comme il faut: seems to mean something like 'as should be'?

It's spoken like this http://www.forvo.com/word/comme_il_faut

And there is some discussion of modern uses here: http://forum.wordreference.com/showthread.php?t=1331743

And a translation and synonyms here: http://thesaurus.com/browse/comme+il+faut

I like this tango/song "comme il faut" (sung in Spanish - es como debe ser), think it helps me get the meaning: http://www.youtube.com/watch?v=BVBWvxfhPTc&feature=youtube_gdata

There also seems to be a more recent song with this title in English but I didn't like the lyrics
