Fairday's Riddles: Repeat, Again, and Again...

Hello, Riddlers! It's been ages. Here's a riddle to ponder. They are all around us, on every possible level of awareness- some I like, some not so much. It's a good thing to see them clearly, then you can decide which ones you want to play with, and those you'd rather not entertain. 

I am that which comes and goes, known too well from head to toes. Circular styles kept in pace, until recognition marks my place. Seen clearly for what I show, you are free to let me go. 

What am I?

I gave you a clue!
