Cos’è questa canzone bulgaro?

It’s probably based on this one: [https://www.youtube.com/watch?v=WmDPOxJsCDA&t=30s](https://www.youtube.com/watch?v=WmDPOxJsCDA&t=30s), which is some mashup of several folk songs with a modern drumm & bass joining them.
But I cannot find the actual original folk song with such lyrics (Марийко мори баш пандаклийско момиче) or melody.
