G Major makes music scary

Found this on In the Style of:

"Another You Tube fad is redoing music in G Major, which lends a pseudo-demonic air. Among the many examples are perennial favourites-or-not Scaryroll (Never Gonna Give You Up), You Are A Pirate from Lazy Town and Satan Knows (aka God Knows from The Melancholy Of Haruhi Suzumiya)."

Can anybody explain to me how this simple transposition manages to make music sound scary?

And while we're at it: Are most pop songs nowadays in major or minor? My bet is on minor, but feel free to prove the opposite.

The meme doesn't actually involve transposing the music to G major, but rather feeding the sound through a G major harmoniser to distort it and make it sound sinister. The phrase "in G major" is misleading; there's nothing particularly scary sounding about a piece that's actually in G major.

^ This. No transposition, just a filter.

Also, most of these videos use the Audacity tool, and its quality is exactly what you'd expect from free software. Adds to that air of ominousness, though.

SINISTER.

I would guess that most pop songs are in a major key, since minor keys sound a bit darker, but I wouldn't know.

A...hem!
