I'm usually on top, or behind a bar
Some sly-sounding people will throw me far
So watch as I pass you by, Hurrah!
I can be sweet yet cold you see
And few will want to count on me

You are looking for a single word with five distinct meanings.
Because there are five meanings and yet I've talked about seven clues, I should perhaps say that three of the clues are used to pin down just one of the meanings. It made for a better rhyme!
The three clues that combine to identify a single meaning are: I'm usually on top. Some sly-sounding people will throw me far.
