Leaked! Mariah Carey’s Horrendous Vocal Track At The Tree Lighting

It seems as though sound engineers are giving Mariah Carey some payback for her tree lighting drama by leaking a track that shows just how horrible her singing is without backup music.

Various sources have reported that Mariah caused lots of trouble at NBC when she showed up 3 hours late to pre-tape her performance for this Wednesday's tree lighting ceremony in Rockefeller Center. Eventually, Mariah did perform on the live show, singing "All I Want for Christmas is You" to open the program.

If this leaked vocal mix is any indication however, folks behind the scenes at NBC still haven't forgiven her for making them stand in the rain waiting for her to show up to the taping.

Listen to the video below to hear what karma sounds like:
