I can'tsay i have A favorite song from BJ.
For me it's just impossible, there are too many i really love and all the other ones i like so much !!!
Just as thomas anderson said, it depends of your mood, i really love wanted, when i really have to name one, i choose this one, but since a week also i'm really 'in' "these days", "and all i want is everything" is running through my head all the time !!! it changes with the days the weeks the months and the years ...
