Susan Boyles
If you haven't seen the U-tube video yet, stop what ever you are doing and goggle Susan Boyles (only because I can't figure out how to do a link). Don't let her appearance fool you, this woman has the most amazing voice I have ever heard. I have watched the video over 20 times now, and everytime, tears come to my eyes. Do yourself a favor and have a listen, she is absolutely inspiring.
