A long shot but worth a try!

it was a track around in the mid 90's i think which was kind of ambient dream music with just a woman singing la la la in it, often used as sort of a stoner song and common in films... if you have any ideas please let me know its really bugging me! I think it was by a french band .

all i can think of is the french band called air.
but cant think what track it is called..sorry
air are an electronic band whose music can be ambient.
good luck finding the track
