Uh... Well, what seems to me is they tried to add a bit of African sound. If you find some popular songs from various African countries, you will hear that guitar is very prominent /just like in this new version, not only because they like it so much, but probably because production is so old school or of a low quality so the guitar sounds like it sounds here, in this new version. I am scared this will be too much for average European ears. It is almost non-listenable, the guitar seems so random and very annoying. Like they play this song and let someone practice its guitar while the song is on.
I like the song, but not this version. There is a huge potential for Czechs for fantastic stage show (the song is very different compared to other entries this year), I just hope they will rethink and sit down with cold heads. I don't like this.
