News / Doda - Kaczynski - Tusk - any connection? [17]

So i just finished watching "teraz my" on itvn. Donald Tusk was on for an interview then at the end he was surprised by a visit from Doda who sang for him.

The interviews said something about "dzikie rozkoszy" prior to the performance.

Does anyone know what rozkoszy means? And is there a connection/significance between doda and tusk? What about the song? It just seems like i'm missing out on something...
