I was probably exaggerating when I said you can't listen to a certain song during a certain time of year. :P But, for me, there IS music that I associate more with different seasons, both because I listened to a ton during the season, it was the first time I heard it during that time, or (remember, synesthesia, smurf yeah, man) it sounds like autumn.

Like, bros, I still listen to Sufjan Stevens in summer, but his music is late autumn/early winter to me. And lots of grey, rainy weather. Etc etc.
