It's not the same though...

Depends on how good your memory is. I had to have a couple wisdom teeth taken out a couple months ago. While waiting on the anesthetic to knock me out I kept replaying a song in my head to see when I stared losing it. I got through the entire thing about 3 times before my mind started to drift. After surgery, my son was taking me home, and I pulled out my phone to see if I had the song right. I was pretty loopy afterward, and he took me into a pharmacy, supposedly under my instructions. I really don't remember that too much... Drove a toy car around on a shelf making car noises or something, so he tells me. If I could remember it I'd probably be embarrassed. But anyhow, even at work I can playback entire albums in my head.
