"I came out here to tell you
it rains in heaven all day long,
I want to find you so bad,
to let you know I’m miserable up here without you"
To me, it sounds like, wherever you are, even in such a good place, or at least one you love or you think you could feel good (as heaven), you can't feel entirely happy ("it rains in heaven all day long") if you're not with the one you love :) that's why i really believe, wherever you are, if you're with the one you love, everything will be fine...
