I have a bunch so I figure there are others out there that can not hear a certain song or album without thinking of someone, someplace or something from their past. Like I said I have tons but the two biggest are the songs I remember from when I was driving back to the hospital to bring home my kids when they were first born. I can't hear these songs without thinking of those days so they have basically become the theme songs for my kids. For my daughter it is "Tiny Dancer" by Elton John For my son it is "Soul Meets Body" by Death Cab For Cutie. Either one of these songs almost brings a happy tear to my eye.
