Do You Have A Background Music?

I was looking for new Christmas songs that I could listen to without getting a thousand different versions of Let It Snow when I came across Owl City's Christmas Song.  When I listened to it, I found myself recalling lines, images, and pages from Dash and Lily's Book of Dares involuntarily.  I always said that reading a Levithan work (even a collaboration) makes me play a background music in my head, and I used to hear December 2 Chapter VII while reading Dash and Lily.  But when I heard this Christmas song, I felt that it was even more perfect because yes, the story of Dash and Lily happen during the holidays and Lily loves Christmas, Dash hates it, all the more making this song appropriate. 

Listen to it, to see what I mean:

I did not want a video with visuals, might interfere with the images from the book that come rushing in my head.

But even if I'm not reading a Levithan book, I still hear music while reading a book sometimes, especially if it's really good and really gets into me.  While reading When You Reach Me by Rebecca Stead I heard Polite Dance Song by The Bird and the Bee.  When I was reading Wintergirls, I was hearing What It Feels Like for a Girl by Madonna.  As for what I'm currently reading, for Delirium I hear The Time by the Black Eyed Peas.  Okay, so it's not that appropriate, especially with the "dirty bit" thingy interrupting my thoughts every now and then, but that's what my brain plays and I can't do anything about it, unless I could get brain surgery, and I wouldn't want that.

How about you?  Do you associate any book with a particular music?  If you do, what song do you play in your head for what you're reading now?
