I find listening to music on my mobile device (an iPod nano, purchased new in April after various misadventures You might remember from a previous post) very isolating. In an uncomfortably scary way. I'm insensitive to aural stimuli so I cannot monitor my environment like I like to. It turns out I use my ears an awful lot when I navigate the physical and social world. Listening to podcasts somehow does not have this effect. Probably because songs are more solid sound than a conversation. Anyway, it's great for when I want to utterly dissociate from my environment, but that is very rare (despite what You might think, loyal reader).
