It's interesting, I always begin my study sessions with the music on. However, I notice that as time passes, my listening activity fluctuates based on my productivity. If I'm really focused on a task, I'll notice that my music will most likely be turned off. On the other hand, if I'm goofing around, my music is almost always on. That suggests that music actually doesn't help with my productivity and if I'm really trying to focus, I'm probably going to involuntarily turn off any distractions.
