Riddle of the Day

[Gizmokid2005]

I'm as small as an ant, as big as a whale.
I'll approach like a breeze, but can come like a gale.
By some I get hit, but all have shown fear.
I'll dance to the music, though I can't hear.
Of names I have many, of names I have one.
I'm as slow as a snail, but from me you can't run.


What am I?

ANSWER (Congrats F1, and no it wasn't the same riddle, but it was the same answer): Shadow

NEXT RIDDLE:

When I asked her how old she was, she smiled and said cryptically:
"The day before yesterday I was 22, but next year I'll be 25."
What is her birthday and when was the date of our conversation?
