To continue on my music-is-a-form-of-communication rant, I recommend you read and/or listen to this short piece by Andre Codrescu.
In this piece, he describes listening to his wife’s ipod after his dies and the world that opens up to him after doing so. I like the potential of this. I like the thought that our choices of what to put on our ipod communicates our lives to other people and that those choices impact their lives as well. Call me idealistic, but I find it a beautiful concept.
