like music that you hear and it reminds you of a movie or a particular scene in a movie 
havent thought about it much but the 3 that come to mind are...
Cría cuervos (1976) - "Porque te vas"
http://www.youtube.com/watch?v=25ckdkg1xCw
Lawn Dogs - "Dancing in the dark"
cant find the mooning scene on youtube lol
and of course...
Leon (1994) - "Venus as a boy"

but it would be cool to get a list of songs together that have featured in girl movies so please add your own if you like
