Like everyone else I get songs in my head and can’t get them out. But they sound different these days. I am not making this up. A couple weeks ago, the music in my head started to sound different — more detailed, with a wider stereo “soundstage” (that’s such a silly sounding term). I thought maybe someone had slipped me something good in my diet coke or something. When I told Carrie on Thursday, she thought it was probably because so much of my music listening has been on headphones this fall. Between the commutes to and from campus with the iPod, and the headphones at my desk (since Carrie’s in the same room and may not want to listen to music while she’s writing), I have spent a lot more time on headphones.
