[Serbia] Konstrakta - In Corpore Sano
The most risky and unique artistic entry, this is masterpiece.
This song is at least about the health system. The main theme of this song is a dictatorial or quasi-dictatorial political system.
Listeners are especially confused by the word "knjizica" (medikal insurance). That word does not mean medical insurance, but a membership card as a sign of belonging to one political party. There was a membership card in the communist system (and I believe it still exists) and everyone who has succumbed to an ideology has a membership card (´´knjizica´´). This is how the party marks its soldiers. They must be identical, look perfect and propagate party ideology at all costs.
An "artist" is an ordinary man / woman who does not have a party card and is therefore an enemy.
At the beginning, she says "An artist must be healthy", which means that people with their souls and bodies must belong to that political system, they must be party soldiers.
But ´´ It is fortunate that there is an autonomic nervous system ´´ that controls the heartbeat without our will, and the heart says that such an ideology is completely wrong.
The artist has complete confidence in what her heart feels and that is why she does not have a memberschip card, which is why they cannot follow or control her.
Then she says "An artist CAN be healthy" and no longer "MUST be healthy" which means that a free man / woman can CHOOSE whether he will have a membrership card or not.
The constant pressure of the dictatorial regime is reflected in the end of the text
 ´´in corpore sano,in corpore sano, 
   in corpore sano,in corpore sano,
   in corpore sano, in corpore sano´´  
The artist is finally broken and finally looks like a party soldier ´´Corpus je sanus´´-the body ist healthly und  ´´So what do we do now? ´´.
   ´´Animus tristis in corpore sano
     Mens desperata in corpore sano
     Mens conterrita in corpore sano´´
Then her spirit becomes perverted and destroyed ....
and in the end she asks the question to everyone again ´´So what do we do now?´´.
Here is an explanation behind the lyrics and performance:
Pontius Pilate washed his hands before the multitude, saying, I am innocent of the blood of this just person. This was to show the crowd he did not want Jesus dead but ordered his death because that is what the people wanted. He was washing his hands of the responsibility. The whole stage is a metaphor. She represents the health system washing hands of responsibility for artists without health insurance.
Mens sana in corpore sano (A sound mind in a sound body). The point artist is trying to make is that news media write and talk about health, supplements, diet, beauty, exercising... Meghan Markle was mentioned because in media there was an article about the most important issue for the survival of life on our planet, her hair. According to the media, a woman has to be beautiful, the artist has to be beautiful and healthy otherwise can not succeed. And artist asks: What about "Mens sana" part? The media do not care about the state of mind, people's spirit, mental health. On the contrary. Fake news, all sorts of lies are there to make us total idiots, ignorant about what really is happening around us, spreading belief that nuclear war can be won or that Putin is going to back down if enough pressure he is under, unaware of how close we are of destroying our home, Earth. Read lyrics carefully several times, and pay attention to lyrics at the end: 
"A sick mind in a healthy body
A sad soul in a healthy body
A desperate mind in a healthy body
A terrified mind in a healthy body"
