From discovery to defence

These days I seem to use music as way of keeping the world out when I’m on public transport, and I don’t think I’m alone in that use at all. Lots of mobile listening seems to seek to defend us against what’s around us, from having to be disturbed or distracted by our surroundings.

Personally I quite like the idea of music as a way of shielding yourself against the world, but I do remember a time when music was a way of discovering new things, new ideas and concepts rather than something to be hidden behind.

I wonder when I changed?
