Is it just me (probably not) or do people tend to associate certain types of music, albums, or songs with certain periods? Last year, I was into a new band or album every month (list below), so whenever I play, sing, or think about a certain song, memories from that time come back to me.

January - Metallica's first three albums
February - Fear of the Dark, The Book of Souls, The Book of Souls: Live Chapter, and "Still Life" (all Iron Maiden)
March - St. Anger (Metallica)
April - 72 Seasons (Metallica)
May - Hardwired... to Self-Destruct and S&M2 (Metallica)
June - "Breaking the Law" by Judas Priest, "The Dark Ride" by Helloween, and "Crazy Train" by Ozzy Osbourne
July - whatever was playing on the rock and roll channel my dad played on Pandora that month
August - Helloween
September - Avantasia
October - Avantasia
November - Avantasia, especially "The Story Ain't Over"
December - Alestorm

I guarantee you that you could give me a song from one of those albums or bands and I could recall a memory I've linked it to.
