I have a special place in my heart for acappella music (i.e. music made with only voices, no instruments).  I was in an acappella group in college, after all. So I was absolutely blown away by this Beyoncé medley, and I think you will be too!

26 Beyoncé songs, in six minutes.  All with no instruments.  This has to be one of the most talented groups I've ever seen!  Check it out:
