Every Day Is Night

Did he drown her for betrayal? (Just in case, I added a point for that).

He ran away and lost his scarf (it got caught on a branch), and someone else strangled him with the scarf and drowned him. Most likely, it was the sheriff who had been following them. There aren't really any other candidates.

Iron Maiden - Speed Of Light (Official Video) — 2 (the band's name is fitting; you could definitely torture someone with a song like this)|4 (references for the sake of references, not great)
BRUTTO - Середні віки (“The Dark Ages”) [Official Music Video] — 4 (I'm too lazy to Google the lyrics, and it doesn't really appeal to me; the song is also longer than the five minutes allowed by the rules)|3 (not a fan of this kind of music)
TIAMAT - Whatever That Hurts (OFFICIAL VIDEO) — 3 (sounds a bit boring, and I didn't Google the lyrics again)|2 (not a fan of music videos, half of which consist of the singer's face, sorry)
Тор - наш Вася!))) — 5 (a funny song, but nothing more)|5 (I think I've seen this video somewhere before, but it's still funny)
Biting Elbows - 'Bad Motherfucker' Official Music Video — 1 (a bad soundtrack)|3 (it feels very amateurish)
ah ahtaita aikoja karaoke — 5 (mediocre)|5 (the video isn't great, but there's something charming about it)
Richard Marx - Hazard — 7 (I'm not sure I'd listen to something like this, but it works well with the video)|8 (one of the best videos in this contest)
Getter - Head Splitter (Official Music Video) — 1 (not my thing)|3 (the video isn't for me either)
No Devotion - Stay (Music Video) — 3 (a boring, generic song)|2 (and the video is kind of silly)
Skip The Use - Nameless World — 7 (the beginning of the song was a bit off-putting, but it picked up later)|8 (a typical quest from an expedition)
Oomph! - Sex hat keine Macht — 4 (generic)|3 (50% of the video is the singer's face, 30% is an erotic woman, 20% is a simple plot, although the ending is funny)
[MMD] - SIREN - Music Video — 4 (a typical opening from the 2000s)|(the animations look awkward, which is typical for these kinds of videos, and the model and voice don't match well)
Ghoultown "I Am the Night" [OFFICIAL VIDEO] — 5 (frankly mediocre, but catchy)|3 (a mediocre plot and a lot of "noise" with the band members)
