YouTube, like Amazon, is a place where you can find almost everything. Except, unlike Amazon it's free and things can get weird fast.
YouTuber Grün Ling (via PC Gamer) took a number of Hearthstone cards, sampled them their sounds and put them together to the tune of Britney Spears' "Baby One More Time." Ling only worked out the initial chorus for the song, but that's pretty much the entirety of the song… So you aren't left wanting too much more.
The real winner of all the cards is Gadgetzan Auctioneer, as that card is the one with the most important line in the song – 'baby.'
Recently, another YouTuber took initiative and made the latest Gears of War 4 even more emotional.
