Songs that make my heart flutter

I made a playlist, I rarely do but I was just thinking I wanted to listen to a bunch of songs in a row that have been there at pivotal points in my life... first kisses, 99 cent CD's, goth moments, art classes, weird friends, partying in Los Angeles, driving around aimlessly, dancing in my bedroom, daydreaming of crushes, new roommates, starting Wildfox... a lot of life. This collection of songs all mean something big to me, hilarious or not they get me going.

What are your memory songs? lets build an epic playlist.
