If there's any single film in relation to which the giving of a full context for my response to its soundtrack would involve a more dramatic violation of the 'no dwelling on the personal, no sturm und drang' rule which has (mostly) applied to these extemporanea entries than Moulin Rouge, I can't think of it.
I've just spent about ten minutes trying to work out how to express the reasons for this in a way which is neither hopelessly vague nor dreadfully revealing, without much luck. In part, it goes something like this:
1. The film is a huge retrospective landmark for me because of X
2. The music is central to the film, also because of X (or its equivalent in the film)
(If this were a proper argument, it would have a conclusion, but it makes sense to me even without one.)
(Also, there's "El Tango De Roxanne" and its own, separate story.)
So I already knew most of these songs more or less inside out from watching the film or by other means, and it's all very sweeping and swoony (and sometimes sassy), and oh so dramatic and oh so memorable (massive roll call of big names in the world of pop, too)...genius songs, great delivery...oh yeah, and it's all about love, of course.
