For the sad times, Dry Your Eyes by The Streets. It captures the moment of being dumped so perfectly that I choke up when I hear it:
So then I move my hand up from down by my side
It's shakin’, my life is crashin’ before my eyes
Turn the palm of my hand up to face the skies
Touch the bottom of her chin and let out a sigh
‘Cause I can’t imagine my life without you and me
There’s things I can’t imagine doin’, things I can’t imagine seein’
It weren't supposed to be easy, surely
Please, please, I beg you please
She brings her hands up towards where my hands rested
She wraps her fingers round mine with the softness she’s blessed with
She peels away my fingers, looks at me and then gestures
By pushin’ my hand away to my chest, from hers
For optimism, Drive by Incubus. It also reminds me of a special woman in my life.
It's driven me before, it seems to be the way
That everyone else get around
Lately, I'm beginning to find that when I drive myself, my light is found
Whatever tomorrow brings, I'll be there
With open arms and open eyes yeah
