What music takes you back to a specific time period in your life?

Pretty self-explanatory, but I’ll give an example. For me, the music of Good Charlotte (their album The Young and The Hopeless), Greenday (American Idiot), Fall Out Boy (From Under the Cork Tree) Panic! at the Disco (the song I Write Sins not Tragedies) and My Chemical Romance (in particular the song Helena) all define the end of middle school/ beginning of high school period in my life.
I was fourteen and had just lost someone I loved deeply for the very first time. I was also due to move and leave everyone I cared about behind to start fresh in a new town.
So, life was filled with sadness, but hope. I also experienced love for the first time during that time period. It was kind of a paradoxical time!
