I just don't get French pronunciation. There are rules, then there are exceptions to the rules, then there are exceptions to the exceptions... and then when you listen to actual French speakers, it seems like they're just making up their own rules as they see fit.
For example, I'm trying to learn the lyrics to Henri Salvador's Mais non, mais non (known to watchers of The Muppet Show as "Muh-nuh muh-nuh"). In the line Je dois fréquenter que les filles de cinquante ans, the word "filles" is pronounced like "fee". But in Lorsque les filles viennent me taquiner, it's pronounced "fee-yuh". The words que les are pronounced like "cleh" in that first line, but immediately afterwards, it's "kah lay".
ARRRRRRRRGH!
