Only rainbows after rain
the sun will always come again
and it's a circle, circling
around again
it comes around again.

This is a part of a song 'Keep your head up' by Andy Grammer. =D

What I think it means;
That After something bad (rain), something good will happen (rainbows), and good will always happen (sun), It will always come around eventually (it's a circle, circling, around again, it comes around again.)
