Music Time Machine

Okay, so maybe I haven't really invented a time machine, but every once in a while I'll stumble upon a song that comes pretty close to transporting me back in time. I'm sure that there are times in our lives when our souls our more raw, easier to imprint on, when a song or a smell can suddenly become the conduit for all sorts of emotions. 

Yesterday I saw a link to the top 100 songs of 1993 and was amazed at how viscerally my body reacted to just reading the titles. There were so many of them that filled me with the most strange mix of longing and a magical hope for the future. If I could bottle what it felt like to be a teenage girl, that would be it...

What songs take you back in time?
