Holiday - 

Waiting - 

 Love this. 
Lucky Star - 

Sorry - 

 A predictable choice, but you can't deny the riff and groove is irresistible. 
Die Another Day - 

Nothing Really Matters - I'm glad this made the list. The bridge is one of Ray Of Light's finest moments. 
Till Death Do Us Part - Cute song, but extremely climatic at the same time. 

Where Life Begins - Excellent song. Madonna's voice really fits this jazz/trip-hop fantasy. 

Oh Father - Madonna's most beautiful ballad next to "Promise To Try."
I'll Remember - 

 The song might be a bit 
bland, but there's a hidden energy that makes all the way better. And she sings so beautifully in it. 
  
So far only "White Heat" and "I'll Remember" have made it from my list.
I suppose I was not the only one who voted for "Drowned World".
