I don't think I could ever switch off my thinking. Is it possible to do so? The closest I think I get is when I'm travelling somewhere or just hanging out listening to music. Its nice to just listen. Takes focus off everything, well almost...
...your mind starts piecing things together. Making connections. To memories, the first time you listened to a song. If you can relate to it in anyway. Or maybe its just me. Imagination, thinking, reflecting.
Sometimes it brings perspective. Sometimes epiphany, Sometimes rest.
But for that time it seems like all that is happening at that moment in time, is the song is playing, and then there's you, listening.
