1. You Look So Fine by Garbage

http://www.youtube.com/watch?v=4jmk1Mlmnck

I admit that this list is skewed to songs that came out in my life time with some exceptions and that if I was born in a different era this list would look entirely different. But when it comes to favorites songs there are always attached to experience associations; especially those that occurred during ones teen/young adult years. There is actually neurological basis for that; the great book This Is Your Brain on Music has an entire section about it: http://www.amazon.com/This-Your-Brain-Music-Obsession/dp/0525949690
