I always seem to associate songs with things I do when I listen to those songs.

Example 1: When I would play Legend of Dragoon I would always listen to Question by System of a Down. Now everytime I play it I can hear that song in my head, or when I hear that song I can see LoD in my head.

Example 2: When I am on TFF I used to listen to A Little Piece of Heaven by Avenged Sevenfold, and many Breaking Benjamin songs. Now when I go through the site I hear those songs in my head, or vise versa.
