Or more like Artist's, I think it'll be the Wonder Girls. They went on tour with the Jonas Brothers which were sold out concerts. Many people who are opening acts become big (Lady Gaga was an opening act, now look at her). They've had great exposure such as The Wendy Williams Show and So You Think You Can Dance. Even their videos on youtube have over 2 million hits each. I don't know, but I have a feeling their cd will be in the top 30, maybe even top 25.
