I'm not sure if anyone's noticed, but there's a lot of multiplayer games lately (over 4,000 at this post). Problem is many of them are empty rooms, and I'm not sure why/how they are there. As shown here below, they all appear to be hosting the same song, and the room titles are also the same. I'm just wondering what happened, hopefully it's just a glitch, but I feel it needed to be pointed out.
