Worst record ever?

I had the misfortune of spotting Sarah Vaughan's "Songs of the Beatles" at my local record store and, intrigued, I bought it since it was only $2. I'm still traumatized a few hours after listening to it; who and why would ever release a record that bad? I love Sarah as a jazz singer but her rendition of the Beatles' songs is absolutely atrocious. I just can't believe someone made a decision to actually release it.
