It's nice to see such a positive thread! I'm not in a very positive place in my life right now, so maybe hanging out with you guys will help me get my head back in the right place.
The one song I can think of that helps bring me out of a funk is Pink's "F---ing Perfect."
The lyrics are simple and beautiful (in their own way) and there is the added bonus of being able to yell out the obscenities while you sing along.
In the car.
While strangers in the next car are looking at you funny.
Think about it...if you met a potential mate who was nothing but a bundle of needs, would YOU be attracted to them?
