You sometimes hear that buzzing thing. You've left it on, and it plays music all day long.
Listening to music is nice. Sometimes I need something else to get a reload of motivation and energy. Many days I don't feel like reading the bible, but it is important to me to have some of it incorporated in my day. Those days I don't feel like listening to music, but still want there to be some buzzing in the background. Finding a wonderful bible movie I let it play in the background. I think background noise gives an impact on our everyday lives, so it is important that it gives you a recharge in its own way.
Don't neglect that background noise ;)
