Singers and Light Bulbs?

I'm still trying to figure out what some artists like about light bulbs. have you ever noticed that in a video by Paramore and Red Jumpsuit Apparatus (can't remember what song) and Nickelback- If today was your last day, they are all attracted to the light bulbs like that insects that like the light. I wonder what they like about light bulbs.. hmmmm.. Maybe its like feeling when you look into the light long enough and get that buzzing feeling in your eyes. (that's coming from a person that has a light bulb next to her bed for the purpose of midnight reading and some how ends up staring into the bulb unintentionally and even know when there is a reflection I can't seem to NOT look).. ouuhhhh the wonder of light bulbs.. =D
