Do you have some albums you listen to more often or exclusively in specific season? It happens to me a lot, especially in last few years because I started listening to more genres than before. For example, black metal is almost exclusively my winter music.
You can list few albums you listen more often in one season than in others, or just the albums that remind you of specific time of the year.
Spring - my indie season; maybe it's because I started listening to it in Spring few years ago, I don't know
The Smiths - Queen is Dead, Neutral Milk Hotel - In the Aeroplane Over the Sea, The Antlers - Hospice
Summer - more often than in other seasons I listen to plain simple heavy music; slightly windy but hot days always remind me of Gojira because the day was like that when I saw them opening for Mastodon and Slayer (first metal show I ever attended)
Gojira - L'Enfant Sauvage, Mastodon - Once More 'round the Sun (listened to it a lot that summer it came out and saw them supporting it in summer a year later)
Fall - nothing specific really but there are few albums I like to listen to when it rains and Fall is the season when it rains a lot here
Elliott Smith - Either/Or, Bon Iver - For Emma, Forever Ago
Winter - as I said, Winter is my dark/black metal season for obvious reasons
Agalloch - Ashes Against the Grain, Woods of Ypres - Woods 5: Grey Skies & Electric Light
