Question about score

I just watched it on Youtube, and the music was shocking https://www.youtube.com/watch?v=454nNoD6-TI, completely out of sorts with the action in the film, and really, really over the top, intrusive, grating etc etc.

Then I thought that it was simply so bad, that it had to be a mistake. So I looked around and found another version, again on youtube, https://www.youtube.com/watch?v=H3X94UkD1-s and the music was just right - matched the musicians, had character and soul and charm... and was just so different from the first score.

I think I'm about to anwer my own question here, but are there actually two scores for this, or did some muppet on Youtube just stick on a mostrosity for whatever their own perverse reasons were? What really confuses me are the comments below the awful music, saying how great the music was. Glad I took time to find the other versio, as on the first one, I was all set to give it a really poor rating.
