This is a very bad thread, not because of anything that anybody posted but because it is far too easy to create a bad song that all too many people have. Somebody could post something that his neighbor wrote while drunk off his ass, and it could stink worse than the local friendly dump after a blaze, and that could be the "worst song ever," but what if someone had one that was worse than even that? Of course, this is all subjective, so maybe it's not so bad a thread after all.
As for that Jamez Bond one, Yatta (another Japanese original) is worse I think. Catchier too.
