Fans of the 2008 X Factor contender Diana Vickers will be happy to hear that she is finally getting some material out (it's about time). Once is the first single off her debut album, Songs from the Tainted Cherry Tree, and it is quite a proper pop tune. Diana's vocals are easily distinguished and familiar to those who followed through TXF 2008. At first hear it may sound like one of those synthesized pop garb, but Diana pulls it through with her distinctive, odd-yet-enthralling voice.
