I know some people can’t fathom the idea of having any type of noise as they write. I do that sometimes, mostly by mistake. Up until I realize there’s no other noise than the clicks of my keyboard and it just starts grating my nerves. If sometimes I choose to listen to my own music, I often come to find it a little distracting. Especially when a song I particularly love, or haven’t heard for a while, starts playing. Singing along while you’re trying to write doesn’t work really well. I know, I’ve tried!
