10/10 - or close enough that it doesn't matter...scintillatingly good of-the-moment pop, genuinely exciting in a way that you feel in your stomach - a shiny aural package wrapped up with all the bells and whistles, a hook a minute, and sold by the girls themselves with enough personality to be convincing. For me, "Biology" and their gigantic cover of "I'll Stand By You" still stand out, but none of the 11 other songs on the cd are far behind.
