Recently I'm going through a phase of not listening to my mp3 player on the bus. I take it to work every day but just don't feel like putting the headphones in. Quite happy to listen to the world going by.
I'm still mentally humming whatever song I really like that day. And invariably it's there on my iRiver if I want to listen to it, but I'd rather just have it go round my head.
I'm like this occasionally. Does anyone else have phases where they open their ears and let the world in?
