Rebecca Black - who, like it or not (there are plenty of both) burst on the scene with her song/video "Friday," 'dropped' her new single and video today. It's called "My Moment."
Black is 14 years old, so be nice.
Greyson Chance became a star on youtube singing Lady Gaga's Paparazzi at a school event. After a gazillion or so clicks, he was invited on The Ellen show, where DeGeneres promised to help him begin a music career.
It seems the promise has helped.
