I listen to music all the time, when reading, sleeping, thinking. I find that it helps me control my emotions, which is so hard for me. For instance, if I'm feeling really depressed, I'll play Coldplay, if I need to get angry when I'm lifting, for instance, I'll play Tool or At the Drive In, before I go to sleep I usually listen to trip-hop, Radiohead, or some other dreamy music. I like to play music when I'm reading, and usually when I'm done with a book, I let a song replay and that song associates the feeling I got from the book. Whenever I play that song again, that feeling recurs in me.
