For me, I put some headphones on and listen to some music on my favorite music. It seems to help stop me from getting distracted by the nosies around me
most of the time it's the same with me. there are moments though when i'm actually distracted by the music itself. so it depends
I normally put on an Ambient Music Station in iTunes, and fullscreenwhatever I am doing, and hide the taskbar and turn off all alerts.
