Answer:
I am black and white and full of fuzz
I am an activity involving pins flying in the air.
I start with āeā end with āeā. I have whole countries inside me. What am I?
I cannot be felt seen or touched. Yet I can be found in everybody. My existence is always in debate. Yet I have my own style of music.
Whoever made me doesn't want me. Whoever bought me doesn't need me. Whoever uses me doesn't know me. What am I?
No matter how little or how much you use me, you change me every month.
