My OCD totally is reflected in how I listen to music. I will put a CD in the car and play the same song over, and over again. Last weekend I had to drive an hour away and I played the same song at least 10 times. Crazy, but I can't help it. I do it all the time. I think it's comforting because I know what is happening. It's like at night I can't fall asleep without watching tv. But, I have to watch the same series every night. I've seen each episode a trillion times so I can close my eyes (and still visualize what is happening), while I am listening. That is how I fall asleep everynight. I recently started taking trazadone which also puts me to sleep. My T told me that now that I am on meds for bedtime I should try to not watch tv. I haven't tried it though.
