2012-2015 Looking for a Polish carol/pastoral

I remember excerpts from two carols or songs by one and the same band (I can't remember the name).
It was on YouTube around the year 2012-2015.
Here are excerpts from the refrain of 1: "But remember they are there, they are in our hearts longing for them, today the little Lord is born, he will lead them to heaven's gates."

Here are excerpts from 2 of which I remember little of the text: "Dark night bad Bethlehem quiet guests.....
The Lord God announces...the birth of a son (king?) and the Messiah.
Glory in the highest to God and on earth peace to men. We praise You blogiskawimy You we glorify You we praise You."

It was some little known band, only one photo as if it was an album cover some night and a star of Bethlehem I think.
Please help it sank completely into the ground.
