It's that time of year where songs from every genre get mashed up with Christmas songs.
Whether you love it, or hate it - we're sharing it with ya.
The YouTube channel named William Maranci Mashups has mashed together Metallica's 'For Whom The Bell Tolls' with Mariah Carey's 'All I Want For Christmas Is You.'
We think it's actually kinda good, but also definitely probably something that should not exist.
One of the top comments on the video says, "this sounds like Metallica did a Christmas album and it went horribly wrong."
