"The prototype, the one and only Queen. By far the most successful female artist of all time, with good reason. Looks and moves better than most 20-year-olds. Ultimate moments: too many to mention"
"Top girl band with plenty of attitude who've produced some of the best pop music this century. Could easily take McFly or Westlife in a fight. Ultimate Moments: Freak Like Me, Hole In The Head"
"They've put the fun back into the charts with their terrific tunes and fabulous pouting. And where are One True Voice now, eh? Ultimate moments: No Good Advice, Something Kinda Ooooh"
"From the moment she appeared gyrating in her school uniform, her status was assured. Currently seems to be going through a 'trailer trash' phase, sadly. Ultimate moments: Baby One More Time, Toxic"
"At her best when she sticks to her pop roots, she comes unstuck when she tries to prove herself as an 'artist'. Ultimate moments: Better The Devil You Know, Love At First Sight"
"Spent years in her sister's shadow, but later carved out her own identity as a dance diva. Had a massive boob job to celebrate her divorce in 1997. Ultimate Moments: All I Wanna Do, I Begin To Wonder"
"Like a more aggressive, rockier version of Madonna. Most straight men seem terrified of her; could probably take Mike Tyson in a fight. Ultimate Moments: Get This Party Started, Stupid Girls"
"The original cool rock chick. Effortlessly smouldering, she just didn't give a damn what people thought of her. Ultimate moments: Heart of Glass, Rapture, Atomic"
"How could I forget Abba? Agnetha and Frida are still huge icons 25 years after the band split. Ultimate Moments: just about everything they ever released"
