Music in our heads.

I inserted both headphones into my ears; The sideways triangle, I pressed. "Fallin" by Macklemore (Ben Haggerty), a small town hip-hop artist from Seattle, Washington, came on. With the volume cranked up all the way, his crisp voice in my head began to make me think. If our brains have the ability to think of and remember things so clearly, why does the limit seem to stop at music? We can paint a vivid picture in our head and remember it just as we see it, but can't play a song over and over in our head. As human beings, we can remember the lyrics and are tempted to hum it. Why is it that we can close our eyes and dream and see things we have or haven't seen and look back at it, but are unable to listen to a song and store it inside our heads for later playback? With our eyes wide open our minds can zone out, but our ears never can.
