Like the deserts miss the rain

I’ve always wondered about the metaphor “like the deserts miss the rain”… what is that supposed to mean? On the one hand, it doesn’t rain in the desert, so maybe the deserts miss the rain a lot. On the other hand, if it rained in the desert, then it wouldn’t be a desert any more, and that would destroy what the desert is, so a desert doesn’t miss the rain at all.

I don’t get it. Nice track though.
