Since the audio is in german, I think it could be a bit disappointing for my english audience but maybe you can grasp the feeling of the song:
Its a song about being nothing special and taking life as it is, be it good or be it bad. The chorus struck me (roughly translated):
"Many laugh only because they don't want to weep,
what did the life do to you?
Do you want a better the world,
start with the one you see in the mirror!
Every tear contains a rainbow,
only in the darkness you can't see it.
I know the stars are above,
and a small shine is enough for me"
So long,
