Kind of odd question...

Ok, so I have a list of dj's that's about a mile long, and I'm looking to shorten it. I've looked at a lot of old threads on the subject, so I know who everyone does recommend, so now I'm asking if there are any DJ's out there that you would NOT recommend? Either a DJ that you've used yourself, or that you've seen at another wedding. I'd love to hear why you wouldn't recommend them, for any reason, annoying MC, not a good mix of music, whatever. If possible could you list what company, (also the MC if you remember), and why you didn't like them? I realize a lot of ladies love MC's who get the crowd working, and some people love DJ's who just play the music, and barely talk. I'm up in the air about that but I'd love to hear what you ladies have to say. Thanks!!
