Query: Pleasent surprise

I don't know why I bought this album. I was impulse buying I guess. The only thing I heard about her was that she was teh opening act for BSB's so I figured why not. What a nice surprise this album turned out to be. Krystal has a great voice and has put together an edgier more daring pop album. Standout tracks include Supergirl and My Religion, funky tracks that really showcases her wonderful vocals. She has original songs and an original style that make her standout from the rest of the pop princesses. Is it better than Britney or Christina, maybe not, but it's an impressive debut that won't disappoint the fans of the teen pop phenom.
