Thanks for that post - I think I probably need to wean myself off using them (it will be hard to give up). I never used to, until I started an 8 mile commute. I'm the sort of person who constantly needs to be plugged in, with an OST to accompany my life. I need to employ Ennio Morricone and orchestra to follow me about and respond to my moods. At a discrete, safe distance of course. But then there is the trouble of the zone-out that happens when I have no music and I'm on a familiar route. I get home after a hard day's work with no memory of my journey home. Does anyone else get this? Like you've been on autopilot all the way home. What is more dangerous? Autopilot or loud earphones?
