Alexandra Burke won the X Factor in 2008, and her winner's single "Hallelujah" was the fastest selling single in Europe (until Cheryl snatched that record). Her first album "Overcome" was successful, debuting at #1 and spawning four #1 singles. Her second album, however, underperformed. In June 2013, she separated from her label due to creative differences. Is her music/voice underrated? I think so. Alex has an amazing voice, and has served SEVERAL bops. She needs more success in the industry
