"Round And Round"

Round and round
With love we'll find a way just give it time
Round and round
What comes around goes around
I'll tell you why

I've never been particularly fond of the cliche "what comes around goes around" - it has a pleasing rhythm, but it falls apart on closer examination. Presumably, it means "you get what you give", but if so, then like "you can't have your cake and eat it too", it's written backwards. Either way, it's always just said as a statement of fact, without regard to whether or why it's true. Why would something that comes around also go around? Where is it coming from, and where is it going?

So here comes Ratt to explain the phrase. Or so they claim. They quite brazenly do not deliver on the promise to tell us why. We're left hanging and thus it remains a mystery. My hopes are cruelly dashed; it's like an arrow through the heart.
