Idolator

We're suspicious of the claim made in this article in the webzine Smith: The piece's compiler, Rich Knight (can't really call it "authorship," can you?), says that he "scour[ed] approximately 4.2 billion" karaoke videos to come up with the 21 doozies offered up for delectation and favorite-voting. But aside from a certain former Idolator, we have to admit we can't think of anyone crazy enough to watch even 21 of these clips, so it's close enough for us.
