The same holds true for songs, possibly even more so. It's uncanny how often a song will come on the radio and share a message that I need to hear right at that very moment. My playlist is full of songs that hold special meaning to me. Some remind me of where I've been, some relate to where I am at the moment and some point to where I need to go.
I might be able to live without a lot of things, but music isn't one of them.
